Answer: 255 cm squared
Step-by-step explanation:
the area of the rectangle is length x width. 22 x 10 = 220.
the sides of the triangle are found by subtracting the sides of the rectangle.
22 - 12 = 10 and 17 - 10 = 7.
the area of the triangle is base x height / 2. so 10 x 7 / 2 = 35.
add the area of the rectangle and the area of the triangle.
220 + 35 = 255.
