How do you use equations to solve probelems about the area of rectangles parallelegrams and trapozoids and triangles

Knowing how to find the area of a parallelogram helps us find the area of a triangle.

We can dissect the triangle into two parts -- one of them a triangle, and one of them a trapezoid -- by slicing it parallel to the base. If we cut the height exactly in half with that slice, the two parts fit together to make a parallelogram with the same base but half the height.

So base x half-height gives the area of the triangle. A similar dissection shows half-base x height. Either of them reduces to 1/2 bh.

The parallelogram's area is base x height, but that is twice the area of the triangle, so the triangle's area is 1/2 of base x height, as we saw with the dissection method.

(As always, pick a "base" and measure the height perpendicular to that base, from the base to the opposite vertex.)

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an
