Question

How would i do this surface area problem? picture is included

Answer 1

`SA=210cm^2`

Explanation:

Comment if u can't understand :)

1. Find area of triangle.

`A=(1)/(2) bh`

`A=(1)/(2)(6)(9.9)`

`A=(1)/(2)(59.4)`

`A=29.7`

2. Identify how many triangles are there.

There are 5 triangles.

3. Find area of total triangles.

`A=29.7(5)`

`A=148.5`

4. Find area of pentagon.

`A=5((1)/(2)bh)`

`A=5[(1)/(2)(6)(4.1)]`

`A=5[(1)/(2)(24.6)]`

`A=5(12.3)`

`A=61.5`

5. Add area of total triangles and area of pentagon.

`SA=148.5+61.5`

`SA=210`
