Question

What is the answer to 3?

Answer 1

Explanation:

First, you have to find the perimeter of the base. You do that by adding all the sides,

There are two sides that are 13 mm and two sides that are 6 mm
13 + 13 is 26
6 + 6 is 12
26 + 12 is 38

Now you have the perimeter. Now you have to multiply is by the highest

So 38*14 (532)

If I understand it correctly

Answer 2

the answer for number 3 is 18
