Question

A greeting card is 7 cm long and 4 cm wide find its perimeter

Answer 1

Answer: add all the sides of the greeting card

Step-by-step explanation: in this case

Perimeter = 4 + 7 + 4 + 7 cm

= 22 cm

Answer 2

Length(l) = 7 cm

Breadth(b) = 4 cm

∴ Perimeter = 2(l+b)

                    = 2 (7+4)

                   = 2 × 11

                  = 22 cm

∴ The perimeter of the greeting card is 22 cm
