What is the area? Please help!!!

anyanavicka [17]

Answer: 96 ft²

Step-by-step explanation:

This figure can be divided into two rectangles:

The first rectangle has dimensions 6 ft by 14 ft.
The second rectangle had dimensions 4 ft by 3 ft.

Find the area of both rectangles:

The first rectangle: 6 × 14 = 84 ft²
The second rectangle: 4 × 3 = 12 ft²

Add them together to find the total area of the figure:

84 + 12 = 96 ft²
