Answer:
Mr. Meglio need to purchase 39 square feet of carpet.
Step-by-step explanation:
Given:
Total number of steps = 13
Length of each step = 1 foot
Width of each step = 3 foot
We need to find the square feet of carpet does Mr. Meglio need to purchase.
Solution:
First we will find the area of each step.
area of each step is equal to length times width.
framing in equation form we get;
area of each step = 
Now amount of carpet required in square feet we multiply number of step with area of each step.
framing in equation form we get;
Amount of carpet required = 
Hence Mr. Meglio need to purchase 39 square feet of carpet.
