Question

2) The perimeter of a rectangle is 40 m. The breadth of the rectangle is 4 m
less than 5 times it's length. Find the length of the rectangle.​

Answer 1

Answer:

Length = 4m

Step-by-step explanation:

Given,

perimeter = 2(L + B) = 40m & breadth = (5L) - 4

⇒ 2L + 2B = 40

⇒ 2(L + 5L - 4) = 40

⇒ 6L - 4 = 20

⇒ 6L = 24

⇒ length = 4m

⇒ breadth = 5(4) - 4 = 20 - 4 = 16m
