Question

The animal shelter is building three equal sized rectangular dog runs on the back of their building. The length of the adjoining runs needs to be 3 times their total width. The shelter has 156 feet of donated chain link fencing for constructing the runs. No fencing is used against the building. a. Write the equation to find the dimensions of the dog runs in terms of w. b. What are the outer dimensions of the dog run addition (in feet)?

Answer 1

Step-by-step explanation:

animal shelter is building three equal-sized rectangular dog runs on the back of their building. The length of the adjoining runs needs to be 3 times their total width. The shelter has 156 feet of donated chain link fencing for constructing the runs.

 

No fencing is used against the building.

a. Which equation can be used to find the dimensions of the dog runs (where w represents the total width of the runs)?

Choose:

 

 2w + 2(3w) = 156

 4(3w) + w = 156

 

 4(3w) + 2(w) = 156

 4(3w) • 2w = 156

 

b. What are the outer dimensions of the dog run addition (in feet)?Choose:

 

 19.5 by 58.5 feet

 9 by 27 feet

 

 11 by 33 feet

 12 by 36 feet
