Answer 1

Answer:

10 units

Step-by-step explanation:

Given that,

The area is modeled by the equation as follows :

$A=-l^2-10l+300$

Where

l is the linear dimensions of the frame.

Put A = 100

So,

$-l^2-10l+300=100\\\\-l^2-10l+200=0\\\\l=10,-20$

So, the linear dimension of the frame is equal to 10 units.
