Answer:
900.
Step-by-step explanation:
1) the initial area is: A₀=0.5*base*h;
2) the final area is: A=0.5*(5*base)*(5*h).
It means, that 25A₀=A, then A=900 [cm²].
-.127, -12, .33, & 45/10 are the answers.
3.643 x 10^-1 would be the answer
Those usually mean the variable for the side length for a triangle.
