Ok;
1. Area is base times height.
Here shown, the base is 18cm and the height is 11cm. Don't be fooled by the 14cm for it is just the leg of a triangle not full height!!
18*11=198cm^2
2. Divide by two. We just caculated the area of the rectangle. Now we know a triangle is half of a rectangle's area so divide by 2!
198/2= 98cm^2

Answer:
if y=6x then 3x-6x=21
-3x=21
x=-7
Let x be the original side length of the square
P=2(l+w)
70=2((2.5+x)+(2.5+x))
70=2(5+2x)
70/2 = 5+2x
35-5=2x
30=2x
15=x
Therefore, the original length of the square was 15"
