Vivian needs to know the area of her backyard so she can order landscaping materials. We have split the backyard into a triangle and four rectangles as shown in the diagram:
rectangle ∆ABC
rectangle CBED
rectangle DMLG
rectangle GFKJ
rectangle NEHI

Part A
To find the area of ∆ABC, find the lengths of base BC and height AB.
