Answer and Step-by-step explanation:
X is equal to 51.
This is because the two sides of the triangle are congruent, so the base angles are congruent.

Area as a function of width, w is:
a(w)=(w-25)^2+625
for maximum area, the width will be:
a'(w)=2(w-25)+0=0
solving for w we egt
2w-50=0
2w=50
w=25 m
given that the perimeter is 100, the length will be:
100=2(L+W)
solving for L we get:
L=50-W
but W=25m
hence
L=50-25=25 m
thus the maximum area will be:
A=L*W=25*25=625m^2
The answer to this is d*2/8
Estimate this product first. 7 times 2 would be 14; 7 times 3 would be 21. So the actual product must be about halfway between 14 and 21, or 17.5.
The actual product 7*2.6 comes out to 18.2 (which is fairly close to 17.5, but not close at all to 14).
