Question

PLZ NEED THIS URGENT LIKE NOW 20 POINTS Gabriella plans to purchase six laying hens. Her family will enjoy the fresh eggs for breakfast. Gabriella wants to create a rectangular enclosure for her chickens. Her dad gave her 90 feet of fencing. Gabriella decided that two of the side lengths would be 15 feet long. What could be the length of the other two sides? Let r represent the length of each of the other two sides.

Which of the equations below best represents the situation?

Question 3 options:

a.90 = 30r + 2


b.90 = 30 + 2r


c.30 + 1/2r = 90


d.30r + 1/2 = 90

Answer 1

b) 90 = 30 + 2r

90 are the feet of fence overall

30 (15*2) are the feet she's already used

2r are the feet she hasn't used yet

Answer 2

b.
`90=30+2r`

Explanation:

We are given that

Gabriella's father gave her fencing of length =90 feet

Length of each side of two equal side =15 feet

Let length of each side of other two equal sides=r

We have to find the equation which represents the best situation.

Perimeter of rectangle =
`2(l+b)`

Perimeter of rectangular enclosure=length of fencing

Using the formula

`90=2(15+r)`

`90=30+2r`

Hence, the required equation which represents the situation best is given by

`90=30+2r`

Option b is true.
