The length of a rectangular screen is 15 cm. Its area is 180 sq. cm. Find its width.​

Answer :

  • Breadth be x

[tex]\\ \rm\hookrightarrow LB=Area[/tex]

[tex]\\ \rm\hookrightarrow 15x=180[/tex]

[tex]\\ \rm\hookrightarrow x=180/15[/tex]

[tex]\\ \rm\hookrightarrow x=12cm[/tex]

Let the width be x

Area = Length × Breadth

180 = 15× x

180=15x

180÷15=15x÷15

12=x or x=12

  • The width is 12 cm...~
