S triangle =ah÷2

=8×6÷2

=48÷2

= 24(c 132 1)

S parallelogram =2S triangle

=2×24

= 48(c 132 1)

S parallelogram = ah

h = s \a

=48÷ 10

=4.8 cm

S trapezoid =(a+b)h÷2

=( 10+ 16)×4.8÷2

=26×4.8÷2

= 62.4(c 132 1)

So the area of the shaded part is: S=S trapezoid -S triangle.

=62.4-24

= 38.4(c 132 1)
