Shawna has been saving and now has exactly enough money to pay for the pink carpet that she wants in her room. She has $219.70. Each wall in her room has a length of 13 feet. a) How many square feet of carpet will she need? b) What is the cost for each square foot of carpet?

169 feet²

$1.30

Step-by-step explanation:

Given that :

Amount Shawna has = exact cost of carpet = $219.70

Length per wall = 13 feets

a) How many square feet of carpet will she need?

Number of square feet of carpet :

13 feets * 13 feets = 169 feet²

B.) Cost of each square foot :

Total cost / number of square feet

$219.70 / 169 feet²

= $1.30

ratio is 2 : 9

the answer is three

13.5 : 3
