Question

5. The length of a rectangle is 15 m more than its breadth. If the perimeter of rectangle is 80 m, find the dimensions of the rectangle
​

Answer 1

Answer:

Breadthof rectangle = x

Length of rectangle = x + 15

Perimeter = 2 (l + b)

80m = 2 ((x + 15) + x)

80m = 2 (2x + 15)

80m = 4x + 30

80 - 30 = 4x

50 = 4x

50/4 = x

12.5 = x

x + 15

12.5 + 15 = 27.5

VERIFY :- 2 (l + b)

2 (27.5 + 12.5)

55 + 25

80

Therefore, Dimensions of rectangle are 27.5m and 12.5m
