Answer:
the perimeter is simply 2L + 2W
So lengthy 8.3
2(8.3) + 2(w) =22.4
16.6=2(w) =22.4
2(w) = 5.8
w = 5.8 divide by 2
The width is 2.9
Given:
The area of a rectangle = 14 square units.
The side lengths are a and b.
To find:
The value of b.
Solution:
We know that, the area of a rectangle is:
The area of the given rectangle is:
On further simplification, we get
Divide both sides by 7.
Therefore, the value of b is 6 units.
Answer:y=5
Step-by-step explanation:
Add 3 to both sides
Simplify
Then, subtract 2y from both sides
Answer: 1/9 pizza portions
Step-by-step explanation:
