Question

The length of a rectangular plot is 10m, more than its breadth. If the perimeter of the floor is 170m, what is its length. ​​please say

Answer 1

Answer:

47.5

Step-by-step explanation:

let length be l and breadth be b

l = b+10

perimeter = 2(l+b)

170 = 2(b+10+b)

170 = 2(2b+10)

170 = 4b+20

170-20 = 4b

150 = 4b

b = 150/4

b = 37.5

l = b +10 = 37.5+10 = 47.5
