**If the rectangle is reduced in half, us know have a triangle. So the area would certainly be half the area of the rectangle.Let"s usage the formula in part examples.Ex. 1) calculate the area the the triangle.Ex. 2) calculation the area that the triangle.Ex. 3) determine the area the the triangle.Ex. 4) The area that the triangle is 32 cm2. Recognize the height.To assist visualize what this trouble is asking, attract the other half so the it creates a rectangle.**

This rectangle would have actually an area that 64 cm2.A = bh64 = 10(x)x = 6.4 cm

Let"s testimonial the steps.Step 1: dual the area that the triangle. (This "undoes" the dividing by 2.)Step 2: divide the new area by the provided side length.
