Step-by-step explanation:
hi , you can see here we have a rectangle without a triangle :
area rectangle - area triangle = area of the shape
Area of the triangle= L x l
=4 x 2
=8
Area of the triangle = 
=
=1
So we do : 8 - 1 = 7
I hope it is gonna be helpful,
have a nice day.

Complete the square.
Use de Moivre's theorem to compute the square roots of the right side.
Now, taking square roots on both sides, we have
Use de Moivre's theorem again to take square roots on both sides.
