Question

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

Answer 1

• Breadth be x

`\\ \rm\hookrightarrow LB=Area`

`\\ \rm\hookrightarrow 15x=180`

`\\ \rm\hookrightarrow x=180/15`

`\\ \rm\hookrightarrow x=12cm`

Answer 2

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...~
