Solution, The given figure can be divided into 3 shapes that is one rectangle and two trapeziums. Area of the rectangle = l*b = 50*10 = 500 cm². Area of trapezuim = (10+30)*10/2 = 200 cm².
How do you find the area of a given figure?

How do you explain area?
Area is the term used to define the amount of space taken up by a 2D shape or surface. We measure area in square units : cm² or m². Area is calculated by multiplying the length of a shape by its width.
How do you find an area of a square?
The area of a square is equal to (side) × (side) square units. The area of a square when the diagonal, d, is given is d2÷2 square units. For example, The area of a square with each side 8 feet long is 8 × 8 or 64 square feet (ft2).
What is an area example?
For example, in a rectangle we find the area by multiplying the length times the width. In the rectangle above, the area is 2×4 or 8. If you count the small squares you will find there are 8 of them. (See Area of a rectangle.)
What is area mean in math?
The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.
What is area in math 3rd grade?
Area refers to the amount of space a two-dimensional figure takes up. One-dimensional figures have no volume. One can find the area of a rectangle by counting individual square units or by multiplying the length and width of the figure.
What is the area of the rectangle?
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
What is area of square and rectangle?
The length and breadth (Width) of the rectangle should be known in advance. Length and breadth are multiplied and the result obtained is the required area. The unit of area is square of the unit of its length and breadth.
What is the area of the figure in square units?
Area is measured in “square” units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor. Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.
What is the area of irregular figures?
To find the area of an irregular shape, we first break the shape into common shapes. Then we find the area of each shape and add them. For example, if an irregular polygon is made up of a square and a triangle, then: Area of irregular polygon = Area of Square + Area of Triangle.
How do you write an area?
A = L * W where A is the area, L is the length, W is the width, and * means multiply.
What is the area of a figure that covers 7 unit squares?
Answer: Area covered by full squares = 6 x 1 = 6 sq. units.
What is the area of the cube?
Surface area of cube is the sum of areas of all the faces of cube, that covers it. The formula for surface area is equal to six times of square of length of the sides of cube. It is represented by 6a2, where a is the side length of cube.It is basically the total surface area.
What is the area of this parallelogram?
The formula to calculate the area of a parallelogram is given as Area of parallelogram = base × height square units.
What are the examples of rectangle?
Examples of Rectangle Shaped Objects
- Laptops. If you look at a laptop, it has four sides, where the opposite sides are parallel to each other and are equal in length.
- Books.
- Cell Phones.
- Door.
- Chocolate.
- Table Top.
- Bed.
- Curtain.
What is square formula?
In geometry, the square is a shape with four equal sides. The area of a square is defined as the number of square units that make a complete square. It is calculated by using the area of square formula Area = s × s = s2 in square units.
Why we use square in area?
Why is Area Expressed in Square Units? The area of a shape is the number of unit squares required to completely cover it. Therefore, it is measured and expressed in square units.
