Question

what is the area of the polygon given below? a. 378 square units b. 580 square units c. 525 square units d. 756 square units

Explanation:

Step1: Find height of left rectangle

$14 + 14 = 28$

Step2: Calculate left rectangle area

$9 \times 28 = 252$

Step3: Find base of middle rectangle

$27 - 9 - 7 = 11$

Step4: Calculate middle rectangle area

$11 \times 14 = 154$

Step5: Calculate top small rectangle area

$7 \times (14 + 3) = 7 \times 17 = 119$

Step6: Sum all areas for total

$252 + 154 + 119 = 525$

Answer:

C. 525 square units
