i am building a rectangular table top. the perimeter is 22 ft. the area is 24feet squared. what are the dimensions of the tabletop
Answered by Reiny
let the length and width be x and y respectively
2x+2y = 22
x+y = 11
y = 11-x

area = xy
xy = 24
x(11-x) = 24
-x^2 + 11x - 24 = 0
x^2 - 11x + 24 = 0
(x-3)(x-8) = 0
x = 3 or x = 8
then y = or y = 3

the table is 8 by 3
