Question

Find the area of the shape below.
11 cm
14 cm
9 cm
20 cm

Answer 1

Answer: A = 235 cm²

Explanation: The figure has not a regular shape, but we can divide it to other figures that are easier to calculate the area.

For example, we can divide this figure in 2:

1) A square of side 9;

2) A rectangle of sides 14 and 11;

The image below represents what it is described.

Area of quadrilateral is calculated as A = length x width

Since both rectangle and square are quadrilateral, area of each will be

`A_(square)` = 9.9

`A_(square)` = 81

`A_(rectangle)` = 11.14

`A_(rectangle)` = 154

The area of the shape is the sum of each part we calculated:

`A_(total)` = 154 + 81

`A_(total)` = 235

The area of the shape is 235 cm².
