(1)
The perimeter of a rectangle is 94 m. The width of the rectangle is 7 m less than the length. Find the length and width of the rectangle.
-------------------
If use L for length, then perimeter dimensions description is 2L%2B2%28L-7%29=94;

(2)
The perimeter of a triangle is 36 ft. One side of the triangle is 2 ft longer than the second side. The third side is 4 ft longer than the second side. Find the length of each side.
------------------- 

side 1         x+2
side 2         x
side 3         x+4
perimeter      36

%28x%2B2%29%2Bx%2B%28x%2B4%29=36
3x%2B6=36
3x=30
x=10
