Hadley's parents want to build a fence around her play area. The perimeter of the play area is 186 feet. The width is two times the length. Use the formula for the perimeter of a rectangle as one of your equations. What is the length and width of the play area?

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

6mm^3 or .6cm^3
