Answer: 288
Step-by-step explanation:
Split the shape up into a rectangle and triangle (shown in picture).
Find the lengths of the triangle:
Height:
28 - 12 = 16
Base:
16 - 4 = 12
Find the area of the rectangle:
12 x 16 = 192
Find are of the triangle:
(12 x 16) ÷ 2 = 96
Add them together:
96 + 192 = 288
