amm1812

Answer:

x=4.5 inches

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The perimeter of a hexagon is the sum of its six length sides

Let

x ----> the length of a shorter side

y ---> the length of a longer side

The perimeter of the hexagon is equal to

P=4x+2y

P=52\ in

so

52=4x+2y ---->equation A

Each longer side measure 1 in. less than 4 times the length of a shorter side

so

y=4x-1 ----> equation B

substitute equation B in equation A

52=4x+2(4x-1)

Solve for x

4x+8x=52+2\\12x=54\\x=4.5\ in
