Answer:
Area = 230 cm
Step-by-step explanation:
We can split this shape into different parts: a rectangle and a triangle (I attached an image below as a visual aid).
The area of a rectangle is given as:
and the area of a triangle is given as:
Let's first solve for the area of the rectangle. The width of the rectangle is 20cm, and the height of the rectangle is 7cm. So, the area is 7 × 20 = 140cm.
Now, let's solve for the area of the triangle. The base of the triangle is 20 cm, and the height of the rectangle is 16 - 7 = 9cm. So, the area is = 90cm.
We add the two values together to get the combined area of the shape. 140 + 90 = 230 cm.
