Answer:
C) 63.2 cm^2
Explanation:
Square: (b)(h) = 6 cm x 7.2 cm = 43.2^2
Subtract 10 from 6 to get the width of the rectangle.
Rectangle: (b)(h) = 4 x 2.8 = 11.2 cm^2
To find the triangle, subtract 7.2 with 2.8 and subtract 10 with 6.
Triangle: (1/2)(b)(h) = (1/2)(4)(4.4) = (1/2)(17.6) = 8.8 cm^2
Now, add everything together.
43.2 + 11.2 + 8.8 = 63.2 cm^2
