Question

the area of rectangular plot is 460sq m if the length is 15% more than its breadth find the perimeter ​

Answer 1

Step-by-step explanation:

area = 460m²

l × b = 460m²

given l = b + (15/100)b

l = (115/100)b = 1.15b

(1.15b)×b = 460

1.15b² = 460

b² = 400

b = 20

l = 1.15b = 23

perimeter = 2( l+b)

perimeter = 2(20+23)

perimeter = 86 m
