Answer: 220.5 ft^2
Step-by-step explanation:
You separate it into shapes and sum the area of those. I made a triangle 15 by 15, a rectangle 4 by 15, a smaller rectangle 4 by 10, and a triangle 4 by 4
So if 240 is 5%, double it to get 480 than multiply it by 10 to get 4800.

Answer:
48 students in science
Step-by-step explanation:
Let r = students in robots club
s = students in science club
r+s = 84
s = r+12
Substitute the second equation into the first
r+(r+12) = 84
Combine like terms
2r+12 = 84
Subtract 12 from each side
2r = 84-12
2r = 72
Divide by 2
r = 72/2 = 36
We need to find s
s = r+12
s = 36+12
s = 48
There are 48 students in the science club
