Question

a rectangular region is removed from another rectangular region to create the shaded region shown below. find the area of the shaded region.
(image shows a larger rectangle with dimensions 19 ft (height) and 10 ft (width), with a smaller rectangle of 8 ft (height) and 9 ft (width) removed from it, and a box for the answer with unit ft², along with reset and multiply buttons)

Explanation:

Step1: Calculate area of large rectangle

Area = length × width = $19×10 = 190$ ft²

Step2: Calculate area of removed rectangle

Area = $9×8 = 72$ ft²

Step3: Find shaded area

Subtract removed area from large area: $190 - 72 = 118$ ft²

Answer:

118
