Answer:
Width = 160
Length = 110
Step-by-step explanation:
Perimeter is the sum of all the sides
They tell you that the length is 50 m shorter than the width
so L = W - 50
W = W
540 = W + W + W-50 + W-50
540 = 2W + 2(W-50)
540 = 2W + 2W - 100
540 = 4W - 100
640 = 4W
W = 160
L = 160 - 50
L = 110
Answer: it is A
Step-by-step explanation:
x^2+2x-48=0
x^2+8x-6x-48=0
x×(x+8)-6(x+8)=0
(x+8)×(x-6)=0
x+8=0
x-6=0
x=-8
x=6
