Answer
The equation is $A=h * 1/2h$
The solution is $8$
Work Step by Step
First, we need to know the area formula, which is A = l*w.
Now, the questions said that "w" is half of it's "h" (the l in the equation). w = 1/2h
Put this with "w" in the area formula.
$A = h * 1/2h$
The second part of the problem is to ask for the area of the picture with a height of 4in.
Replace 4 with all of the "h" value.
A = 4 * 1/2(4)
Solve we will have:
A = 4 * 2
And the answers will be:
$A = 8 in.$
