we know that
The surface of the prism is equal to the area of its six rectangular faces
The surface area is equal to

where
B is the area of the base
P is the perimeter of the base
H is the height of the prism
we have



<em>Find the area of the base B</em>


<em>Find the perimeter of the base P</em>


<em>Find the surface area SA</em>

59 = 2(14+x)
59 = 28 + 2x
31 = 2x
15.5 = x
Width = 15.5
