Question

The city is installing fencing around a rectangular space for a new dog-walking park. The length of the rectangle is 2.25 times its width. If the length measures 150 yards, what will be the perimeter of the dog-walking park?

Answer 1

I got 433.33 Yards but can't figure out how they got that answer

Answer 2

so 2*150=300 and then what?

Answer 3

sorry, its not correct

Answer 4

ok

Answer 5

Answer 6

we have:
width= length/5= 150/2.25=...?

Answer 7

so 150 divided by 2.25 and then what?

Answer 8

the requested perimeter is:
\[\large L + W + L + W = 150 + W + 150 + W = ...?\]
where:
\[\large W = \frac{L}{{2.25}} = \frac{{150}}{{2.25}} = ...?\]

Answer 9

150

Answer 10

we have:
\[\large W = \frac{L}{{2.25}} = \frac{{150}}{{2.25}} = 66.667\]
so:
perimeter is:
\[\large 150 + W + 150 + W = 300 + 66.667 + 66.667 = ...?\]

Answer 11

thankyou!!
