the area of the retangler piece of foil is 11 1/4 square inches its length is 4 1/2 inches what is the width of the foil?
2 answers:
Answer:
The width of the foil = w = 2.5 inches
Step-by-step explanation:
We know that the Area of a rectangular piece:
Here:
- 'w' is the width
- 'l' is the length
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

Answer:
6√3
Explanation:
Before we begin, remember the following:
Now, for the given:
75 can be written as 25*3
This means that:
Applying the above concept, we can find that:
Now, we know that:
√25 = 5 (we ignored the negative value)
This means that:
√75 = 5√3
Finally, we can compute the needed sum as follows:
√75 + √3 = 5√3 + √3 = 6√3
Hope this helps :)
