$\blue{\underline{\bf{Given-}}}$

• Length of the rectangle => 7 cm
• Breadth of the rectangle => 5 cm

$\bf{\blue{\underline{Steps-}}}$

Perimeter of rectangle ==||> 2 (l + b)

                                      ==||> 2 (7 + 2)

                                      ==||> 2 x 9

                                      ==||> 18 cm

∴ the perimeter is 18 cm.
