Question

An Ice Hockey rink is a rectangle with a perimeter of 174 meters. The length is 9 meters more than twice the width. What equation describes this problem? (Remember that the perimeter is twice the length plus twice the width)

Answer 1

Answer:

Let width be x metres

so, length is "9 metres more than twice the width" --> 9+2x

So, perimeter is x + x + (9+2x) + (9+2x) = 174

6x + 18 = 174

6x = 156

 

x = 156/6

x = 26m

width = 26m

length is therefore 9+2(26) --> 9+52 --> 61m
