Two sides of a pentagon shaped yard are each 5.8 meters long. The rest of the sides measure 3.1 meters each. How much fencing material will be needed to enclose the yard?

20.9 meters

Step-by-step explanation:

Given:

Two sides of a pentagon shaped yard are each 5.8 meters long.

The rest of the sides measure 3.1 meters each.

Question asked:

How much fencing material will be needed to enclose the yard?

Solution:

As we know:

There are five sides in a pentagon:-

Two sides are = Each of 5.8 meters long

Rest three sides are =  Each of 3.1 meters long

That means five sides are = 5.8, 5.8, 3.1, 3.1, 3.1

Now, we will find perimeter of this pentagon shaped yard to find material required for fencing.

Perimeter = Sum of all sides

                =  5.8 + 5.8 + 3.1 + 3.1 + 3.1

                = 20.9

Therefore, 20.9 meters fencing material will be needed to enclose the yard.
