Answer:
140 inches
Step-by-step explanation:
Find the area of the square.
4 + 10 = 14 (Length)
11 + 4 = 15 (Breadth/Width)
Area = 14 x 15 = 210 inches
Find the area of the 2 unshaded squares in the square.
Area of square at the top = 4 x 4 = 16 inches
Area of square at the bottom = 6 x 9 = 54 inches
Add the 2 squares of the area together.
16 + 54 = 70 inches
Now deduct the area of the huge box by the area of the 2 unshaded squares.
210 - 70 = 140 inches
