Question

Perimeter help please quick !

Answer 1

`\boxed{ \bold{ \huge{ \boxed{ \sf{x = 4.4}}}}}`

Explanation:

Given,

Length of the rectangle ( l ) = 3x + 5

Breadth of the rectangle ( b ) = 2x - 1

Perimeter of the rectangle ( P ) = 52

Finding the value of x

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

⇒
`\sf{52 = 2(3x + 5 + 2x - 1)}`

⇒
`\sf{52 = 2(5x + 4)}`

⇒
`\sf{52 = 10x + 8}`

⇒
`\sf{10x + 8 = 52}`

⇒
`\sf{10x = 52 - 8}`

⇒
`\sf{10x = 44}`

⇒
`\sf{ (10x)/(10) = (44)/(10) }`

⇒
`\sf{x = 4.4 \: }`

Hope I helped!

Best regards!! :D
