What is the perimeter of the triangle shown on the coordinate plane, to the nearest tenth of a unit? 20.6 units 22.7 units 25.6 units 27.6 units

we know that

the perimeter of a polygon is the sum of the length sides

in this problem we have a triangle

so

the polygon has three sides

Let

the perimeter is equal to

The formula to calculate the distance between two points is equal to

Step 1

Find the distance AB

substitutes the values in the formula

Step 2

Find the distance BC

substitutes the values in the formula

Step 3

Find the distance AC

substitutes the values in the formula

Step 4

Find the perimeter

the perimeter is equal to

substitutes the values

therefore
