Question

Area of rectangle is twice the area of a square, the square has sides 7cm, find the area of rectangle

Answer 1

Area of the square = side x side
Area of the square = 7cm x 7cm = 49cm

Area of the rectangle = Area of the square x 2
Area of the rectangle = 98cm

Answer 2

`\fbox{\large\sf{ Question}}`

Area of a rectangle is twice the area of a square. The side of a square is 7 cm , find the area of the rectangle

`\fbox {\large\sf{Given} }`

• Area of a rectangle is twice the area of a square.
• The side of a square is 7 cm

`\fbox{\large \sf{ Need to find}}`

• Area of the rectangle

`\fbox{\large \sf{Solution}}`

It is given that the area of the rectangle is twice than the area of a square so first we will calculate the area of the square.

We know,

`❒ \: \boxed{\large\rm{ Area_((square)) = Side × Side }}`

Substituting the value of side = 7 cm in the formula

`\large\sf{ Area_((square)) = (7 × 7) {cm}^(2)} = 49 {cm}^(2)`

Now we will calculate the area of the rectangle

Area of a square = 49 cm²

Area of a rectangle is twice the area of a square.

`\large\rm Area_((rectangle))(2 × 49) {cm} ^(2) = 98 {cm}^(2)`

`\rule{59mm}{2pt}`

`\large\rm Final \: Answer`

• Area of the rectangle = 98 cm²
