Question

I need to know what the surface area of the figure is it also says to round to the nearest hundredth where necessary. please help!

Answer 1

`A\text{ = 73.60 m}^2`

Step-by-step explanation:

Here, we want to get the surface area of the given figure

From what we have, there are 3 faces and a base

For the faces, we have triangles with a base of 4m and a height of 11.1 m

For the base, we have a triangle of base of 4 m and a height of 3.5 m

We find the area by adding the surface areas of each of the shapes

The area of a triangle is half the product of the base and the height

Mathematically, we have that as follows:

`A\text{ = 3\lparen}(1)/(2)*4*11.1)\text{ + }(1)/(2)*4*3.5`
`A\text{ = 66.6 + 7 = 73.60 m}^2`
