The area of a rectangular lawn is 880 square feet. If the length of the lawn is

4 feet less than

twice its​ width, find the dimensions of the lawn.

22 ft x 40 ft

Step-by-step explanation:

Let x be the width

x(2x - 4) = 880

2x² - 4x = 880

x² - 2x = 440

complete the square by adding (b/2)² to each side

x² - 2x + 1 = 440 + 1

(x - 1)² = 441

x - 1 = ± 21

x = 1 ± 21

as a negative length does not make sense

x = 1 + 21 = 22 ft = width

L = 2(22) - 4 = 40 ft length

the two may have that, even a breakdown is probably offered

my answer is$ 12

step-by-step explanation:

because 15 -2=12
