Answer 2

How do you calculate the area of a rectangle?

Answer 3

@reemii

Answer 4

\(WL=A\)
Since \(W=4\) always. and you want to find out when \(A \lt 100\)
\(4L \lt 100\)
\(L \lt \frac{100}{4}\)
\(L \lt 25\)

The lengths which the area is less than \(100 cm^2\) is \(L \lt 25\)

Answer 5

W=width
L=length
A=area
