<h2>Answer:</h2>

This is easy. All you need to do is set up a proportional relationship.

A proportional relationship uses variables to show similarities, in this case, in triangles.

$\frac{2}{3} = \frac{x}{6.3}\\\\3x = 12.6\\\\x = 4.2$

x represents the missing side.

A formula for finding the area of a rectangle is A =l.w. If you know the area (A)

AlekseyPX

Answer:

$w =\frac{A}{l}$ .

Step-by-step explanation:

The formula for finding the area of a rectangle is A = l.w, where A is the area, l is the length and w is the width of the rectangle.

This formula is used to find area when l and w are known.

Now, if area A and length l are known the width w will be given by the formula $w =\frac{A}{l}$ .

Therefore, width = area by length. (Answer)
