Answer:
f = 6 cm, g = 8 cm
Step-by-step explanation:
<u><em>Area of ABCE = 60 cm²</em></u>
While,
<u><em>Area of ABCD = 48 cm²</em></u>
This shows that,
<u><em>Area of ΔADE = 12 cm²</em></u>
So,
<em>Where b is DE = 4 cm and h is AD which needs to be found</em>
=> 2h = 12
<em>Dividing both sides by 2</em>
=> h = 6 cm
<em>Since AD is parallel to BC and is also equal, So,</em>
=> AD = BC = 6 cm
So, f = 6 cm
<em>Now we need to find g</em>
Since ABCD is a rectangle and the area of it is 48, so we'll find g as:
Length * Width = 48
6 * g = 48
Dividing both sides by 6, we get
g = 8 cm
