Question

9. Susan bought 66 feet of fencing for her rectangular garden. The width of the garden 3 less than its length. What is the width of her garden? *

Answer 1

s call X the width of her garden and Y the length.

Since Sasan bought 66 ft of fencing, we can write the following equation:

2X + 2Y = 66

Additionally, The width of the garden is 3 less than its length

X = Y - 3

So, replacing the second equation on the first one and solving for Y, we get:

2 (Y - 3) + 2Y = 66

2Y - 6 + 2Y = 66

4Y - 6 = 66

4Y - 6 + 6 = 66 + 6

4Y = 72

Y = 72/4 = 18

Then, replacing this value on the second equation we get:

X = Y - 3

X = 18 - 3

X = 15

So, the width of her garden is 15 feets.

Answer: 15 feet
