Question

The length of a rectangle poster is 10 more inches than three times its width. The area of the rectangle poster is 88 square inches solve for the dimensions of the poster

Answer 1

the length is (3x + 10) inches. Since the width cannot be negative, we ignore the negative solution. Therefore, the width of the poster is approximately 3.27 inches. Therefore, the dimensions of the poster are approximately 3.27 inches by 19.81 inches.
