Learning Task 2: Read and analyze each problem below then answer the questions that follow.

1.)Consider the trapezoid on the right . if you cut the trapezoid along the dotted lines,

You divide it into two figures. Now, answer the following questions:

Into what shapes has the trapezoid been divided?

What are the height and base of each shape?

Find the area of each shape and add them together,

How does this sum compare to the area of the trapezoid?

b, 20cm

ih 16 cm

bz 25 cm

2.)Study the drawing on the right.Name at least two familiar figures you can see in the drawing.

8 cm

Find the area of the figure. If this drawing shows half of the drawing for a

Façade of one storey building, draw the whole building. What familaiar

Figures can you identify in the new drawing? Find the area of the new figure.

Answer:

Into what shapes has the trapezoid been divided?

➡Triangle

What are the height and base of each shape?

➡B1=20 cm,h=16cm

B2=25cm,h=16cm

Find the area of each shape and add them together.

Triangle 1 Triangle 2

➡A=1/2 BxH = A=1/2 BxH= =1/2(20cm×16cm) =1/2 (25cm×16cm)

=1/2 (320cm2) =1/2 (400cm2)

A=160cm2 A=200cm2

160cm2+200cm2=A=360

How does this sum compare to the area of the trapezoid?

➡The area of 2 triangles is equal to the area of trapezoid.
