Answer:
Shaded area is 55 unitsĀ²
Step-by-step explanation:
Ignoring the white cutout, we have a rectangle of length 10 and width 7 (count the squares in each direction). The area of this larger rectangle is
(10 units)(7 units) = 70 unitsĀ². The white area that we previously ignored has dimensions 3 by 5 units, and thus an area of 15 unitsĀ²
Subtract the latter from the former, obtaining the net area
70 unitsĀ² - 15 unitsĀ² = 55 unitsĀ²
