7 equals Wonders of the Ancient World.
L = 14 and W = 2 would give an area (A) of 28, or 7 (L) x 4 (W) = 28 (A)
Surface Area = 2*(L*W + W*H + H*L) = 2*(7*5 + 5*2 + 2*7) = 2*(35+10+14) = 2*59 = 118 square units.
The "answer" is usually the number that you can put in place of 'W'that will make the statement true.- 7/2 W = 20Multiply each side of the equation by 2:-7 W = 40Divide each side by -7 :W = - 40/7
