Question

Find the area of the shaded regions

• A. $67c{m}^2$
• B. $64c{m}^2$
• C. $65c{m}^2$
• D. $66c{m}^2$

Answer 1

Answer: (B)

$64c{m}^2$

In the above diagram,
BC=20cm,
EF=6+6=12cm,
AE=FD=(BC-EF)/2=(20-12)/2=4cm
EH=FI=EO=FO=6cm.
Here AEHB and FDCI is trapezium.
So area of AEHB and FDCI= 2*(base1+base2)*height/2
$A=(6+10)\times 4$
$A=64c{m}^2$
Answer is option $\left(B\right)$.
