First of all, the formula to find the area of the rectangle=
length×width
In this case, the problem asks us to find the area of the rectangle EFHG, so we need to find the dimensions of that:
length=e+h
or
length=f+i
I would prefer use the first one
Next,
width=d
or
width=j, I would prefer to use this variable since the multiple choices only give us j.
Lastly,
Area of the rectangle EFHG=
(e+h)×j is your final answer. Hope it help!
