Question

Manny has 48 feet of wood. He wants to use all of it to create a border around a garden. The equation 2l+ 2w = 48 can be used to find the length and width of the garden, where l is the length and w is the width of the garden. If Manny makes the garden 15 feet long, how wide should the garden be?

Answer 1

2W=9

Explanation:

You must first get the Length, which is 15, and multiply it by 2 and you get 30. You then subtract 30 from 48 and get 18. Since the equation has 2W, you have to divide 18 by 2, which gets you the answer 9.

Answer 2

width = 9 feet

Explanation:

Here we are given that total length of the wood for the garden is 48 feet only.

The length in represented in the equation given below. In geometry we call it Perimeter.

2l+2w=48

Where l is the length of the garden and the w is width of the garden.

Here also given that , if Manny wants the length to be 15 feet, what will be width of the garden.

In order to find this we put the value of l as 15 in 2l+2w=48 and solve for w

Let us see how

2l+2w=48

2(15)+2w=48

30+2w=48

subtracting 30 from both sides

30+2w-30=48-30

2w=18

Dividing both sides by 2 we get

w=9

Hence the width will be 9 feet
