Question

The perimeter of a rectangular house is 309.2m what is the length of the house if it's width is 71.2m?​

Answer 1

Answer:83.4

Step-by-step explanation:

2(l + b) = 309.2

l + b = 154.6

l = 154.6 - 71.2

l = 83.4

Answer 2

Step-by-step explanation:

p = 309.2m=2 (l+b)

2 (l + b)= 2 (l+71.2)

2l + 142.4=309.2m

2l= 309.2 - 142.4

2l= 266.8

l= 266.8/2

l= 133.4m
