Step-by-step explanation:

Given that,

  • Length = 6y + 10
  • Width = y – 3

[tex]\implies \sf Perimeter = 2(L + W) \\ \implies \sf P= 2(6y + 10 + y - 3) \: units \\ \implies \sf P= 2(7y +7) \: units \\ \implies \red{\sf P= 14y + 14 \: units} \\ [/tex]

Therefore, perimeter is (14y + 14) units.

Solution:-

We have been given to find out the perimeter of a rectangle who is having length (l) = 6y + 10 and width (w) = y - 3 i.e we have here,

  • Length (l) = 6y + 10

  • Width (w) = y - 3

The standard formula for calculating the perimeter of a rectangle is given by,

[tex]\implies\rm{p = 2(l + w)}[/tex]

[tex]\implies\rm{p = 2(6y + 10 + y - 3)}[/tex]

[tex]\implies\rm{p = 2(6y + y + 10 - 3)}[/tex]

[tex]\implies\rm{p = 2(7y + 7)}[/tex]

[tex]\implies\rm{p = 14y + 14}[/tex]

  • The perimeter of rectangle is 14y + 14 units.
