Answer:
The formula for the area of a rectangle is A = L x W, where A is the area, L is the length, and W is the width.
We are given that the length of the rectangle is 8 centimeters and the area is (16x+24) sq. cm.
Substitute these values into the formula and solve for the width:
A = L x W
(16x+24) = 8 x W
16x + 24 = 8W
Divide both sides by 8:
2x + 3 = W
Therefore, the width of the rectangle is 2x + 3 centimeters.
