The width of the mattress is 7.
Give that
- The area of the mattress is 56 square feet.
- The length is 8.
- And, the width of the bed is x + 4.

Area of the rectangle = Length × width
56 square feet = 8 × (x + 4)
56 = 8x + 32
56 - 32 = 8x
x = 3
So, the width is
= 3 + 4
= 7
Therefore we can conclude that the the width of the mattress is 7.
