Question

help please

Answer 1

Perimeter of Rectangle = 2*(width) + 2*(length) = 30

(1/2)*(length) = (width)

Answer 2

wait, what?

Answer 3

That's the information you're given:

"perimeter of a rectangular field is 30 meters"
-> Perimeter of Rectangle = 2*(width) + 2*(length) = 30

"width is one-half the length"
-> (1/2)*(length) = (width)

Answer 4

in more "mathy" equations
it looks like this

2W + 2L = 30
and
(1/2)L = W

Answer 5

You can plug in W = (1/2)L
into
2W + 2L = 30

Answer 6

oh, alright
