Answer:
Width of the house is 15.25 feet.
Step-by-step explanation:
Jason ran around his house = 3 times
In this run he covered total distance = 274.5 feet
Perimeter of the house = 2(length + width)
= 2(30.5 + width)
Perimeter of the house is the distance covered by Jason in one round.
So, distance covered in 3 rounds = 3[2(30.5 + width)]
274.5 = 6(30.5 + width)
274.5 = 6(30.5 + width)
45.75 = 30.5 + width
width = 45.75 - 30.5
width = 15.25 feet
Therefore, width of the house is 15.25 feet.
