Answer:
Option A that is 10x + 2
Step-by-step explanation:
Given that,
Length of the school = 2x - 1
Breadth of the school = 3x + 2
Total length of the fence = perimeter of the fence
= 2 ( L + B )
= 2 ( 2x - 1 + 3x + 2 )
= 2 ( 5x + 1 )
= 10x + 2
So, the length of the fence is 10x + 2
This is the inner length of the fence which actually surrounds the school. To find the outer length we will add 4 in the length and 8 in the breadth.
