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

Step-by-step explanation:

Given, perimeter of rectangle =perimeter of square

so perimeter of square=4×side

4×15=60 cm

now given 60=perimeter of rectangle

60=2(l+b)

60=2(17+b)

60/2=(17+b)

30-17=b

13 cm will be the breadth
