Question

The area of a rectangular piece of land J is 220 square metres.Its width is 12.5.what is the perimeter of the land ?​

Answer 1

`\boxed{ \bold{ \huge{ \boxed{ \sf{ {60.2 \: m}}}}}}`

Explanation:

Given,

Area of rectangular piece of land ( l ) = 220 m²

Width ( w ) = 12.5 m

Finding length of the rectangular piece of land

`\boxed{ \sf{area \: of \: rectangle = l * w}}`

plug the values

⇒
`\sf{220 = l * 12.5}`

Swap the sides of the equation

⇒
`\sf{12.5 \: l = 220}`

Divide both sides of the equation by 12.5

⇒
`\sf{ (12.5 \: l)/(12.5) = (220)/(12.5) }`

Calculate

⇒
`\sf{l = 17.6 \: m}`

Length of rectangular piece of land ( l )= 17.6 m

Finding perimeter of rectangular piece of land

`\boxed{ \sf{perimeter \: of \: rectangle = 2(l + b)}}`

plug the values of length and breadth

⇒
`\sf{2(17.6 + 12.5) }`

Add the numbers

⇒
`\sf{2 * 30.1}`

Multiply the numbers

⇒
`\sf{60.2 \: m}`

Therefore, Perimeter of rectangular piece of land is 60.2 m

Hope I helped!
