Answer:
Step-by-step explanation:
6²+8²=36+64=100=10²
so it is a right angled triangular prism.
surface area=2×(1/2 ×8×6)+(6+8+10)×7
=48+980
=1028 sq. m.
I do believe that the answer is 900.
Steps:
I first set up a proportion, with 8/100 and 72/x (x being the number we are trying to find)
As I was taught, you multiply 100 by 72, which equals 7,200.
Then, I divided 7,200 by 8, which gave me 900.
This is what the proportion process should have looked like:
8/100 72/x
7,200/8
x=900
I hope this helps!
There is no figure to find the area of
