Predict: How do you think the formula for area of a triangle will relate to the formula for area of a rectangle? Do you

think it is the same area formula?

I think is the same formula area. A triangle is half as big as the rectangle that surrounds it, which is why the area of a triangle is one-half base times height.

Step-by-step explanation:

The area of a rectangle is given by the relation length * width. The area of a triangle is given by the relation (1/2) * base * height. Now we know that the two have the same area equal to 150 cm^2. Also, when placed on the same level the tip of the triangle touches the upper edge of the rectangle.
