Question

Use the image to find the area and the permiter

Answer 1

Area = 45 units²

Perimeter = 29.4 units

Explanation:

We can find the area of the shape in two parts.

The first part is the rectangle,

• The area of the rectangle is calculated with the following formula:

w × l

• w: width, l: length

7 × 5 = 35 units²

The second part is the triangle,

• The area of the triangle is calculated with the following formula:

`(1)/(2) * b * h`

• b: base, h: height

`(1)/(2) * 5 * 4 = 10 \: \: {units}^(2)`

To find the area of the whole shape, add both parts up:

35 units² + 10 units² = 45 units²

• Now to find the perimeter of the whole shape, we simply add all side lengths' measures.

9 + 7 + 5 + 2 + 6.4 = 29.4 units
