Katie worked on her science fair project for 2.5 hours on Tuesday and 1.75 hours on Friday how many hours did she work on the project Tuesday and Friday combined?

4.25 hours

Step-by-step explanation:

From the question, we are informed that Katie worked on her science fair project for 2.5 hours on Tuesday and 1.75 hours on Friday.

The total number of hours she worked on the project Tuesday and Friday combined will be:

= 2.5 hours + 1.75 hours

= 4.25 hours

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
