What is the area of the rectangle shown below

(6x -5) ft (3x +10)ft

To find the area of a rectangle, multiply the length by the width.

In this case, the length is 6x - 5 ft and the width is 3x + 10 ft.

Area = (6x - 5) * (3x + 10)
Area = 18x^2 + 30x - 15x - 50
Area = 18x^2 + 15x - 50

Therefore, the area of the rectangle is 18x^2 + 15x - 50 square feet.
