Question

the width of a rectangle playground is 18 meters less then the length find the width.when the perimeter of the rectangle is 84 meters

Answer 1

You would set up the equation as (x)(x-18)=84.

Answer 2

first, solve for x of expression bellow!
2(x+x-18) = 84

i assumed the length is x and then the width be (x-18)

Answer 3

so i got that but im lost now

Answer 4

ok ?

Answer 5

im so cofused do you mind helping please

Answer 6

let the length being l
so than the width will be l-18

but you know that the perimeter of a rectangle you get assuming the length with width two time so wath mean that P = 2l + 2w

but you know that w=l-18

so than P=2l+2w=2l+2(l-18)=2l+2l-2*18=4l-36=4(l-9)

Answer 7

thank you so much

Answer 8

yw

was my pleasure

good luck
