Answer:
20/50=40% So 50 to 70 percent increase is 40%.
20/70=about 28.57% decrease for 70 to 50.
So they aren't the same because the hundred percent are different numbers in this case.
Answer:
Surface Area= 144
Step-by-step explanation:
To find the area of the triangle you would multiply the base times the height and divide it by 2. 9x6/2=27. For one triangle the area is 27. Since there are 4 you would multiply it by 4. 27x4= 108. This will give you 108. Now all you need to do is add the square which is 6x6= 36. 108+36=144.
