Well your equation would be 40 = 2x + 16 so subtract 16 from both sides and that’s 24=2x then divide both sides by two so the length of the rectangle is 12.
Based on the given, there are two ways to know the dimensions of the rectangle. First, by simply drawing the coordinates given in a cartesian coordinate plane, P1(0,6),P2(8,6) by looking at the ordinate the length is 6 units, thru P3 (0,0) and P4 (8,0) and looking at the abscissa, the width is 8 units. The second way is through the distance formula, d=sqrt (X2-X1)2+(Y2-Y1)2. The dimensions are L=8 and W=6

The building is around 14.14 feet tall
a^2 + b^2 = c^2
14^2 + 2^2 = 200
