Practice makes perfect

We want to find the area and perimeter of the given figure. Let's start by identifying our figure!

Our figure is a quadrilateral with two pairs of parallel sides, which makes it a parallelogram. Now we can find the area and perimeter of the parallelogram one at a time.

Area

The area of a parallelogram is the product of its base and its height. In the given parallelogram, if we consider the side with a length of inches as the base, then its corresponding height is inches.

We want to find the area and perimeter of the given figure. Let's start by identifying our figure!

Our figure is a polygon with three angles and three sides. This means that our figure is a triangle. Now we can find the area and perimeter of the given triangle. Let's do it!

Area

Let's start by recalling the formula for the area of a triangle.
