Surface Area is the area of each face added together. For this question lets find the area of one triangle first.
Area of a triangle is base*hight/2, so 6*7/2=21. That was the area of one triangle. We have 4 traingle so we multiply that by for. 21*4=84.
Now, lets find the area of the squre. area of square is side*side or side^2.
So we multiply 6*6=36. that is the area of the square.
To find the surface area, we must add Area of Triangles+Area of Square.
so, 84+36=120
So the surface area is 120
Find the difference between the 2 numbers which will give you the increase from the lower value to the higher. Divide this increase by the original (lower) number and multiply the result by 100 to get the percentage. For us that looks like this:
. Simplifying a bit we have
or 49%, rounded.

Answer:
10%
Step-by-step explanation:
40+5+5=50
50-5=45
45*2=90
50*2=100
100-90=10
