Question

A rectangle has the area equal to that of a square of side 80cm. If the length of the rectangle is 160cm, it's breadth is?​

Answer 1

Given :

• A rectangle has the area equal to that of a square of side = 80 cm.
• The length of the rectangle = 160 cm.

To Find :

• It's breadth ?

Solution :

Let, the breadth of the rectangle be x.

We need to find the area of a square.

Area of spuare = a²

$\implies {(80 \: cm)}^{2} \\ \\ \implies6400 \: {cm}^{2}$

Given that,

Area of a rectangle = Area of a square

That means,

Area of a rectangle = 6400 cm²

Length × Breadth = 6400 cm²

$\implies160 \times x = 6400 \: {cm}^{2} \\ \\ \implies 160x = 6400 \: {cm}^{2} \\ \\ \implies x = \dfrac{6400}{160} \: {cm}^{2} \\ \\ \implies x = \dfrac{640}{16} \: {cm}^{2} \\ \\ \implies x = 40 \: {cm}^{2}$

Hence, the breadth of the rectangle is 40 cm².
