Answer:
Step-by-step explanation:
The area of a trapezoidal prism would be 1/2(B1+B2)H
Answer:
m = 3 * 51 / 34 = 4.5
Step-by-step explanation:
multiply both sides by 51 to isolate m
3t=4s+5 (s=side of square, t= side of triangle)
s=t-3, t=s+3, using this value for t in the first equation gives us:
3(s+3)=4s+5
3s+9=4s+5
-s=-4
s=4
so the side length of the square is 4cm and the area of a square is just s^2
A=16cm^2
