Please helppppppppppppppp

Answer 1

10 units

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.
