Question

The area of a rectangle 144 m long is the same as that of a square having a side 84 m long . The width of rectangal is

Answer 1

area of rectangle =area of square
l×b = side × side
144m× b= 84m×84m
b=7056m^2/144m
b=49m

Answer 2

Given :

The area of a rectangle 144 m long is the same as that of a square having a side 84 m long

To Find :

Width

Solution:

Length of rectangle = 144 m

Let the breadth of rectangle be x

Area of rectangle =$Length \times Breadth = 144x$

Side of square = 84 m

Area of square = $Side^2 = 84^2 =7056 m^2$

We are given that The area of a rectangle 144 m long is the same as that of a square having a side 84 m long

So, 144x=7056

$x=\frac{7056}{144}$

x=49

Hence The width of rectangle is 49
