The vertices of ∆abc are a(-2, 2), b(6, 2), and c(0, 8). the perimeter of ∆abc is units, and its area is square units.

Perimeter : 22.81 to the nearest hundredths

Area: 24 square units

Step-by-step explanation:

The vertices of ∆ABC are located at A(-2, 2), B(6, 2), and C(0, 8).

The perimeter is the distance around the figure.

Use the distance formula to find the side lengths of the triangle and add them up.

The distance formula is

units

units

units

The perimeter is 8+6.32+8.49=22.81 units

The area of this triangle is given by: (see attachment)

square units.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.
