Question

What is the area of this polygon
A=220 cm^2
A=242 cm^2
A=248 cm^2
A=270 cm^2

Answer 1

220 is The Correct Answer

Letter Choice (A)

Explanation:

HERE'S MY PROOF AND MY RESEARCH

Area of a rectangle = width x height

Area of a triangle = 1/2 x base x height

Area of the rectangle = 11 x 18 = 198 cm²

Area of the triangle = 1/2 x (18 - 7) x (15 - 11) = 22 cm²

Therefore, area of the polygon = 198 + 22 = 220 cm²

Answer 2

A = 220 cm²

Explanation:

• Area of a rectangle = width x height
• Area of a triangle = 1/2 x base x height

Area of the rectangle = 11 x 18 = 198 cm²

Area of the triangle = 1/2 x (18 - 7) x (15 - 11) = 22 cm²

Therefore, area of the polygon = 198 + 22 = 220 cm²
