Question

The perimeter of a rectangle is same as the perimeter of a square of side 12 cm. If the length of the rectangle is 13 cm, find its breadth​

Answer 1

Answer:

11 cm

Explanation:

perimeter of square = 4 x 12 = 48cm

length of the rectangle is 13 cm

2(l+b) = perimeter

2(13+b) = 48

13 + b = 24

b= 11 cm

Answer 2

Answer:

Breadth =11cm

Explanation:

Perimeter of square = 4 × side

= 4×12 = 48cm

Perimeter of rectangle = 2×l+b

2×(13+x)=48

13+x = 48/2

13+x = 24

x= 24-13

x=11
