Perimeter & Area Of A Triangle.

By:Pd.1

Benchmark: MA.6.8.2: Use coordinate geometric to represent and analyze properties of geometric shapes.


Definition
Definition!

Perimeter is the distance around a shape.

Area is the space inside or taken up by the shape.

Area=( ) BxH

Perimeter=the sum of all the sides.


Example drawing

5 in

5 in

h=4 in

b=6 in

Example/ Drawing

Perimeter = 16 in(5+5+6)

Area = 12 in2(6x4)/2


Question
Question

Figure out what the perimeter and area of the triangle?

10 in

10 in

h=8 in

b=12 in


Solution
Solution

The area of the triangle is 48in2 because 12x8=96 and then follow the formula and you divide it by 2 and you get 48in2. The perimeter is 32in because if you add all the slides up you get 32in.
