$7, I think. I would not be too sure about it, though.
Answer:
if x gets +2 then y gets 3 taken away
Since we know a square has 4 equal sides
and is equal to to exact right triangles.
USing the formula for Perimeter
l+l+w+w=P or 2L+2W=P
56cm÷4=14 so now we have
(2)14+(2)14=P
P=14cm^2
The slant length on a triangle is equal to L
Slant lenght=14
The answer in simplified form is {5x^2+1}{2x+1}
