Area of the field shown in the figure given below is:

• A. $68c{m}^2$
• B. $70c{m}^2$
• C. $72c{m}^2$
• D. $75c{m}^2$

Answer 1

The correct option is B

$70c{m}^2$

Area ABCDEFG
=Area AJHG +Area HFED +Area JICB + Area ICD
$=(8\times 4)+(4\times 4)+(4\times 3)+\frac{1}{2}(5\times 4)$
=32 +16 +12 +10
$=70c{m}^2$
