serious [3.7K]

Answer:

1. 14 cm

2. 20.4 cm

3. 24 - w

Step-by-step explanation:

Let's start with the last question, as it'll make answering the previous two a lot easier. In the 3rd question, we are asked to create a formula to find the length of a given rectangle, using its given perimeter of 48 centimeters and width of w centimeters.

Therefore, let the length of the rectangle be l, we can construct the following equation:

2l + 2w = 48\\\to2l = 48 - 2w\\\to l = \frac{48 - 2w}2\\\to l = 24 - w


Now we have a formula that defines our length, if given the width of the rectangle. The only thing from here on out is to substitute the given widths to the formula we just found.

1. w = 10 , therefore, l = 24 - 10 = 14.

2. w = 3.6 , therefore, l = 24 - 3.6 = 20.4.
