Answer:
W = 3m
L = 8m
Step-by-step explanation:
given:
L = 2 + 2w
A = 24m²
solution:
A = (L)(W)
24 = (2 + 2w)(w)
24 = 2w + 2w²
0 = 2w² + 2w - 24
0= 2w²/2 + 2w/2 - 24/2
0 = w² + w - 12
( w + 4 ) ( w - 3)
x + 4 = 0 x - 3 = 0
w = - 4 w = 3
w = 3m
L = 2 + 2(3)
L = 2 + 6

0= 2w²/2 + 2w/2 - 24/2
0 = w² + w - 12
( w + 4 ) ( w - 3)
x + 4 = 0 x - 3 = 0
w = - 4 w = 3
w = 3m
L = 2 + 2w
L = 2 + 2(3)
L = 2 + 6
L = 8m
