Problema Solution
A classroom wall has 3 windows each measuring 4 ft x 3 ft. The wall is 24 ft wide and 10 ft tall. What percent of the wall is windows?
Answer provided by our tutors
The area of the wall is:
A1 = 24*10
A1 = 240 ft^2
The area of the 3 windows is:
A2 = 3*4*3
A2 = 36 ft^2
The percent of the windows is:
(A2 / A1)*100 = (36/240)*100 = 15%
The 3 windows are 15% of the area of the wall.
