Formulas for the area of shapes

100

What is the formula for area of a parallelogram?

b x h (base x height)

200

What is the formula for area of a triangle?

b x h /2 (base x height, then divide by two)

300

What is the formula for area of a trapezoid? 

[(b1+b2)x h]/2 (add base 1 + base 2, multiply the height, then divide by 2)

400

True/False: Is the formula for area of a rectangle the same as the area of a parallelogram?

True
