Use area formulas for rectangles, triangles, parallelograms, trapezoids, and composite figures.
Match the shape to its area formula
Problem
A parallelogram has a base of \(12~m\) and a height of \(5~m\). What is its area?
Big Picture
What this problem is really about
Imagine sliding the slanted end of the parallelogram to make a rectangle without changing the covered region. That rearrangement shows why its area is base times perpendicular height, with no one-half factor. Multiply the measurements in their formula roles and use square meters, since the calculation combines two lengths.
