Me find the lateral and the surface area i have to round to the nearest tenths if necessary

Step-by-step explanation:

We have four congruent triangles with base b = 16cm and height h = 12cm.

The formula of an area of a triangle:

Substitute:

The latearal area:

For the surface area we need the area of a base.

The base is a square with side a = 16cm.

The area of the base:

The surface area:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
