Question

The length of rectangle is 3 its breadth its area is 972 square meter find the perimeter of rectangle

Answer 1

Let the breadth of the rectangle be x

Thus,length of the rectabgle=3x

Area of a rectangle=l×b

=>3x×x=972

=>3x²=972

=>x²=972/3

=>x²=324

=>x=18

Thus,breadth of the rectangle=18cm

And,length=3(18)=54cm

Perimeter of a rectangle=2(l+b)

=>2(18+54)

=>2(72)

=>144cm
