How do you calculate the area and the perimeter of a parallelogram and a triangle?

Accepted Solution

for parallelograms:area = b(h)so basically, the length times the height. just like how you would find the area of a square.perimeter: just add all of the sides together.for triangles:area = 1/2(b) x hso half the length multiplied by the height. for example, if the length was 4, you have to use half of that. so that means 2 times whatever the height is.perimeter: again, just add all three sides together
