if theres a perimeter of 28 and an area of 24 what is length and width


Answered by Ms. Sue
Factors of 24:
2 * 12
3 * 8
4 * 6

Which of those will give a perimeter of 28?

Answered by JUDE
12 and 2



a= l x w 12 x2 = 24

perimeter add all sides
12+ 12 +2 +2 = 28
Answered by Damon
to make it easy
L + w = 14
l w = 24
Answered by Henry
2L + 2W = 28.
Divide both sides by 2:
Eq1: L + W = 14.

Eq2: L*W = 24.
L = 24/W.

In Eq1, replace L with 24/W:
24/W + W = 14.
Multiply both sides by W:
W^2 + 24 = 14W.
W^2 - 14W + 24 = 0.
24 = -2*-12, -2 + -12 = -14 = B.

(w-2)(w-12) = 0.

w-2 = 0, W = 2.

w-12 = 0, W = 12.

(L,W)
(12,2)
(2,12)
