To find surface area, you can find the area od all sides and add them together
First, area of an triangle is 1/2 length times width
So you do 1/2 6*9= 1/2 54= 27 The area of the three triangles are 27
27 times 3 is 81
81 plus the base of 15.6 is 96.6
The surface area is 96.6 meters squared
This is a math riddle in which you can only discover the
answer by cracking the given equations and each answer has the corresponding
letters. Nonetheless, the solution to this is the scientist created an
