Answer:

Option A that is 10x + 2

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.
