Answer:
Option H, 120 units
Explanation:
Total rectangle area:
width x length
10 units x 24 units = 240 units
Area of 1 shaded traingle:
A = (height) x (width) / 2
A = (12 units) x (10 units) / 2
A = 120 units / 2
A = 60
Now mutiple A by 2 since we have two shaded regions
60 x 2 = 120
Subtract the entire rectangle area with the shaded area to get the unshdaed area
240 units - 120 units = 120 units
