Answer : The dimensions of table runner will be, 20 inch length and 4 inch width.
Step-by-step explanation :
Let the width of table runner be, x
and, the length of table runner will be, 5x
Given:
Area of table runner =
![80inch^2](https://img.qammunity.org/2020/formulas/mathematics/college/hlzrs4sk9ff6059p6gojdgcfmszn5929a1.png)
As we know that:
Area of rectangle = Length × Width
![80inch^2=(5x)* (x)](https://img.qammunity.org/2020/formulas/mathematics/college/2z405t18vrn4r71txs0hrhnxkn8olc5eto.png)
![80inch^2=5x^2](https://img.qammunity.org/2020/formulas/mathematics/college/uuinswhakm56igh2vp4aqio3zb01amqae3.png)
![x=4inch](https://img.qammunity.org/2020/formulas/mathematics/college/6n5ol1dmquuj20vi9o2npfnzuianaq516g.png)
The width of table runner = x = 4 inch
The length of table runner = 5x = 5(4) inch = 20 inch
Therefore, the dimensions of table runner will be, 20 inch length and 4 inch width.
