Question

1. Perimeter of a rectangle and a square is same. If the side of a square is 15 cm and one side of the rectangle is 18cm, find the area of the rectangle.
Please help

Answer 1

Let length of a rectangle = X cm

Given that

Breadth of a rectangle = 18cm

Side of a square = 15cm

A/C to the question

perimeter of rectangle = perimeter of square

2(l+b)= 4× s

2( X+18)=4×15

X+18= 60/2

X+18=30

X=30-18=12

Breadth of a rectangle =12 cm

Area of rectangle = L×B = 12×18=216cm2

Hence area of a rectangle is 216 cm2.
