We are given that the width of of a rectangular painting is 83 cm and it's area is 7719 cm² and we are asked to find it's length , as we know that the area of a rectangular shape is given by L×B. Where L is the length of the rectangular shape and B is the width/Breadth .Now , applying the same concept in our question we have ;
![{:\implies \quad \sf L=93}](https://img.qammunity.org/2023/formulas/mathematics/high-school/ycfowu94ppcoq7hxyfybupo760jevy3un5.png)
![{:\implies \quad \bf \therefore \quad \underline{\underline{Length=93\:\: cm}}}](https://img.qammunity.org/2023/formulas/mathematics/high-school/a3telltbvbfmc4e0nx158k5ly3eg5io14e.png)
