Jacob is building a fence for his backyard. The length of the fence is 17m and the width is 9 ½ m. How much fencing does Jacob need?

Answer 1

To find the amount of fencing Jacob needs, we can use the formula for the perimeter of a rectangle, which is 2*length + 2*width.

First, we need to convert the width from 9 ½ m to a decimal. We can do this by dividing ½ by 2: ½ ÷ 2 = ¼. So the width is 9 + ¼ = 9.25 m.

Now we can calculate the perimeter: 2 * 17 m + 2 * 9.25 m = 34 m + 18.5 m = 52.5 m.

Therefore, Jacob needs 52.5 meters of fencing.
