# Thread: Area of a rectangle

1. I know that the height is not 2 somewhere around 1.9 or 1.85 which is the f()
It is x = 1.0 and x = 1.5
and the strip of the shaded is 0.5 unit wide

Somehow i can get the asnwer

2. It appears the base $b$ of the rectangle is 0.5 units, while the height is:

$\displaystyle h=f(1.5)=4-1.5^2=1.75$

Thus, the area $A$ (in units squared) is:

$\displaystyle A=0.5\cdot1.75=0.875$
