Area of rectangle is twice the area of a square, the square has sides 7cm, find the area of rectangle
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
\(\fbox{\large\sf{ Question}}\)
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
\(\fbox {\large\sf{Given} }\)
\(\fbox{\large \sf{ Need to find}}\)
\(\fbox{\large \sf{Solution}}\)
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.
\(\large\rm Area_{(rectangle)}(2 × 49) {cm} ^{2} = 98 {cm}^{2}\)
