Question

the perimeter of a rectangle is 66m. one side is 15 m longer than the double other side. setup and solve a system of equations to find the dimensions of the rectangle. pls explain how u got the steps. ty.

Answer 1

*66 m

Answer 2

let one side=x
other side=2x+15
Perimeter=2[(2x+15)+x]=2(2x+15+x)=2(3x+15)=6x+30
6x+30=66
6x=66-30=36
x=36/6=?
this is one side .
find other side by substituting the value of x in 2x+15

Answer 3

what is the value of x?

Answer 4

36/6=6

Answer 5

do i substitute the value of x into the equation 2[(2x+15)+x]=2(2x+15+x)=2(3x+15)=6x+30 to get the answer?

Answer 6

one side=x=36/6=6 m
other side=2x+15=2(6)+15=12+15=27 m

Answer 7

okay ty
