Question

Irina wants to build a fence around a rectangular vegetable garden so that it has a width of at least 10 feet. She can use a maximum of 150 feet of fencing. The system of inequalities that models the possible lengths, l, and widths, w, of her garden is shown.
w ≥ 10

2l + 2w ≤ 150



Which length and width are possible dimensions for the garden?

l = 20 ft; w = 5 ft
l = 20 ft; w = 10 ft
l = 60 ft; w = 20 ft
l = 55 ft; w = 30 ft

Answer 1

Its just a matter of subbing in ur answer choices to see what makes the equation true....the 1st one can already be eliminated because width has to be greater then or equal to 10.

when subbed in, only one works :
L = 20, W = 10

Answer 2

Answer:

B

Step-by-step explanation:

L = 20, W = 10
