Question 316014
Hint: Let W = width and L = length. The perimeter of a rectangle is {{{P = 2L+2W}}}. Plug in {{{P=82}}} to get {{{82=2L+2W}}}. The diagonal 'd' can be obtained through the Pythagorean theorem, which means that {{{d^2=L^2+W^2}}}. Plug in {{{d=29}}} (the given diagonal length) to get {{{29^2=L^2+W^2}}}. So at this point, you have two equations with two unknowns.
