7. A city lot is twice as long as it is wide, If its perimeter is 480 units, what are the dimensions of the lot?
g100num [7]

Answer:

Step-by-step explanation:

P = 480

P = 2 length + 2 width

but we also know that

2width = length

so plug that into the length

P = 2(2width) + 2 width

480 = 4 width + 2 width

480 = 6 width

80 = width

160= length

see?
