Area of the Base

Unit 10: Area

Lesson 2 - Area of Parallelogram

Parallelogram

A 2D shape that has 2 sets of parallel lines, and is slanted.

Base: is your bottom length value. [Length]

Height: How tall a shape is.[Width]

Your height MUST be a 90 degree angle from the base. [Can be measured inside or outside]

Area of a Parallelogram

Area = base x height

A = b x h

Step 1: Plug in

Step 2: Solve
