"The perimeter of a triangle is 28 m. If the length is two more than half the width, find the dimensions of the rectangle."
I'm assuming you're trying to find the dimensions of a rectangle? Well, here goes.
Right now we know that the perimeter is 28 m.
I always use let statements so, let n = width let +1%2F2+n%2B+2+ = length
Then, since it's perimeter, you add 2 widths + 2 lengths
+2n%2B2%281%2F2+n%2B2%29=28+ then solve
+2n%2Bn%2B4=28+ combine the n's
+3n%2B4=28+ subtract both sides by 4
+3n=24+ divide both sides by 3
+n=8+
So, the width is 8 m. and the length is 6 m.
Also: square root of 19843223 is 4454.57
