Answer:

141 units squared

Explanation:

Dashed lines have been added to the figure to help you see one way to cut it into manageable pieces.

Triangle BCD has a base BD of 10 units and a height CD of 6 units. Its area is ...

A = 1/2bh

A = 1/2(10)(6) = 30 . . . square units

Square BEFG has sides of length 6. Its area is ...

A = s²

A = 6² = 36 . . . square units

Trapezoid AGHI has bases of 14 and 16, and a height of 5. Its area is ...

A = 1/2(b1 +b2)h

A = 1/2(14+16)(5) = 75 . . . square units

The total area is the sum of the parts:

total area = triangle area + square area + trapezoid area

total area = 30 + 36 + 75

total area = 141 . . . square units
