The roller skating rink has a perimeter of 150 yards. If the length of is twice as long as the width, what are the dimensions of the rink

Answer: 50 yards by 25 yards

Step-by-step explanation:

rink is also a rectangle

perimeter = 150 yards

length = 2x

width=x

the perimeter of rink is:

p=2 (length + width)

150=2 (2x + x)

150 = 2 (3x)

150 = 6x

x=150 / 6

x=25

so width is 25 yards and length is twice the width which is 2x

length = 2 * 25

length = 50 yards

so the dimension is 50 yards by 25 yards
