Answer:
Step-by-step explanation:
Jarred drew the model below of his backyard. The perimeter of the backyard is 40 feet, and the backyard is 8 feet wide.
his backyard is in rectangle shape and breadth =8
perimeter = 40
but perimeter = 2(l+b)
so
2(l+8)=40
l+8=20
l=12 feet
I'm going to make some assumptions here:
That your sqrt8x= sqrt4+2x means √(8x) = √(4+2x). (There are other interpretations.)
Squaring both sides, 8x = 4 + 2x, or 6x = 4, or x = 4/6, or x = 2/3.
