Question

Find the area of the shape below.
16 cm
7 cm
7 cm
20 cm

Answer 1

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:

$Area = width * length$

and the area of a triangle is given as:

$Area = \frac{1}{2} *base * height$

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 $\frac{1}{2} * 20 * 9$ = 90cm.

We add the two values together to get the combined area of the shape. 140 + 90 = 230 cm.
