# Multiply 2-digit numbers with area models

## Problem

The following area model shows 27, times, 85 broken into parts.
The image is not drawn to scale.
An area model using a rectangle of 4 unequal parts. The first part, labeled A, has a height of 20 and a base of 80. A second part to the right, labeled B, has the same height as part A and a base of 5. A third part, labeled C, is directly below part A and has the same base as part A and a height of 7. A fourth part to the right, labeled D, has the same height as part C and a base of 5.
Find the area of each part.
Aequals
Bequals
Cequals
Dequals
What is the total area?
Be sure to answer all parts of the question.
