Answer:
Step-by-step explanation:
Let the breadth of rectangle be x cm.
length of rectangle = x + 5 cm.
Perimeter of rectangle = 62 cm.
The formula of perimeter of rectangle = 2 ( Length + Breadth)
=> 2(x + x + 5) = 62
=> 2(2x + 5) = 62
=> 4x + 10 = 62
=> 4x = 52
=> x = 13 cm.
Thus breadth of rectangle = x = 13 cm
Length of rectangle = x + 5 = 13 + 5 = 18 cm.
