A = 18 ft²

formula for the area of a rectangle is:

length x width

lets use:

A = l x w

solution by trial and error.

so the area must be 18 ft²

let l be any real number greater than 0 but less than or equal to 18

0 < l ≤ 18

assume any value of l greater than 0 but less than or equal to 18

like l = 3ft

A = 3 x w

18 = 3 x w

w = 6ft

or l = 4ft

18 = 4 x w

w = 4.5 ft

check

A = l x w

for l = 3

A = 3 x 6

A = 18 ft²

for l = 4

A = 4 x 4.5

A = 18 ft²
