Hi!
(the green numbers on the image are the step numbers)
We can solve this using PEMDAS.
I wrote out how I solved it in the image, and here I will go more into detail:
Step 1
Write out the equation
Step 2
Put in the variables
Step 3
<em>Solve:</em>
Parentheses - Multiply
Step 4
Parentheses - Subtract
Step 5
Multiply
Step 6
Add
<em>There's your answer! :)</em>
The answer is 42
Hope this helps! :)

Answer:
Option A is the correct answer.
Explanation:
The given pyramid has 3 lateral triangular side as shown below.
Base of triangle = 12 unit
We need to find perpendicular.
By Pythagoras theorem we have
Perpendicular² = 10²-6²
Perpendicular = 8 unit
So area of 1 lateral triangle = 1/2 x Base x Perpendicular.
= 1/2 x 12 x 8 = 48 unit²
Area of lateral side = 3 x 48 = 144 unit²
Option A is the correct answer.
