Can you help me please.

255

Step-by-step explanation:

Take your rectangle first

22*10 = 220 cm^2

Now your triangle:

The base is 7cm ( 17 - 10), and the height is 10 cm (22-12)

A=10 * (7/2)

A= 35

Now add both together.

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.
