Question

The length of a rectangle is 132 cm and its perimeter is equal to the perimeter of a square with side 100 cm . Find the area of the rectangle.

Answer 1

Length=132 cm

Perimeter of square = Perimeter of rectangle

===
===

4×S=2(l+b)
4×100=2(132+b)
400=2(132+b)
200=132+b
200-132=b
68cm=b

===
===

Area of rectangle= l × b
=>132cm×68cm= >8976cm²

Answer 2

Perimeter of square = 100 x 4 = 400 cm

Now, Perimeter of rectangle = 2 x (L +B)

2 x (132 + B) = 400
264 + 2B = 400
2B = 400-264
2B = 136
and , B = 68 cm

now area = L x B
132 x 68
= 8976 cm²
