Question

The perimeter of a square is twice the perimeter of a rectangle If the perimeter
of a square is 60 cm. and breadth
of the rectangle is 3 cm then find the
length of the rectangle ?​

Answer 1

Answer:- 12 cm

Step-by-step explanation:-

Perimeter of square = 60cm (given)

Breadth of rectangle= 3cm (given)

We know that perimeter of rec. = 2(l+b)

According to question perimeter of square is twice the perimeter of rectangle

So,

60 = 2{2(L+B)

60 = 2{2(L+3)

60= 4L+12

4L= 60-12

4L = 48.

L = 48/4

Therefore, length of rectangle = 12 cm.
