Answer: C - 600cm^2
Explanation:
Area of one triangle:
(12)(5) ÷ 2 = 30
Area of two triangles:
30 x 2 = 60
Area of top rectangle:
Step 1: Figure out side length of triangle by using pythagorean:
√a^2 + b^2 = c
√(5)^2 + (12)^2 = c
√25 + 144 = c
√ 169 = c
13 = c
Step 2: Find area of top rectangle:
(18) x (13)
234
Find area of bottom rectangle:
(18) x (12)
216
Find area of back rectangle:
(18) x (5)
90
Add all the underlined numbers:
Area of two triangles + Area of top rectangle + Area of bottom rectangle + Area of back rectangle
60 + 234 + 216 + 90 = 600cm^2
