Question

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

Answer 1

Step-by-step explanation:

Given,

Perimeter of square = 2×Perimeter of rectangle

60cm = 2×Perimeter of rectangle

>> Perimeter of rectangle = 30cm

Given, Breadth of Rectangle = 3cm

We know, Perimeter of Rectangle

= 2×(Length+Breadth)

30cm = 2×(Length+3)

15 = Length + 3

Length = 12cm

Hence, the length of rectangle = 12cm
