Answer:
The width of the foil = w = 2.5 inches
Step-by-step explanation:
We know that the Area of a rectangular piece:
Here:
Given that area of the rectangular piece of foil:
Area = A = 11 1/4 square inches
= 45/4 square inches
= 11.25 square inches
Length = l = 4 1/2 inches
= 9/2 inches
= 4.5 inches
Using the Area formula
inches
Thus, the width of the foil = w = 2.5 inches
It is d. you can solve the question with Pythagorean
1/3 for the first one, and 3/4 for the second one :)
