The students will be able to:

find and use the area of trapezoids by composing and decomposing into other shapes.

The trapezoid is decomposed into a rectangle and a triangle.

Find the area of each shape.

Rectangle:

A = LW، = 9(10)، = 90

Triangle:

= (3)(10)، = 15

The total area is 90 + 15 or 105 .

The trapezoid is decomposed into a square and two congruent triangles.

Square:

= 7(7)، = 49

Triangle 1:

= (2)(7)، = 7

Triangle 2:

The total area is 49 + 7 + 7 or 63

A = 12

A = b h

A = 72، A = 36

The area is 36

The area is 66

The area is 155,000 .

The area is 648 .

(2)

The height is 4 inches.

The area is 4.5
