Sagot :

Perimeter

====================================

The length of the rectangle is x+5 cm and width is x+2.Find the Preminiter of the rectangle.

Answer:-

  • [tex] \pink{\bold{C. \: 4x + 14}}[/tex]

====================================

Solution:-

Use the formula for finding the perimeter. P = 2(l+w).

  • [tex] \pink{\bold{P = 2 \times (l + w)}}[/tex]

  • [tex] \pink{\bold{P = 2 \times (x + 5+ x + 2)}}[/tex]

  • [tex] \pink{\bold{P = 2 \times (2x + 7)}}[/tex]

  • [tex] \pink{\bold{P = 4x + 14}}[/tex]

Therefore the perimeter of the rectangle is 4x+14.
