Question

find the perimeter of a quadrilateral whose sides is 17 cm and 15cm and 21 cm and 18cm

Answer 1

Answer:

Perimeter = sum of the length of all the sides

Step-by-step explanation:

Sides= 17 cm, 15 cm, 21 cm and 18 cm.

Perimeter= 17+ 15+ 21 +18

               = 71 cm

∴Perimeter of the quadrilateral is 71 cm.

Answer 2

Answer:

71cm.

Step-by-step explanation:

given,

given that,

a = 17cm

b = 15cm

c = 21cm

d = 18cm

perimeter = sum of the length of all the four sides.

perimeter of a quadrilateral = a + b + c + d

                                              = 17 + 15 + 21 + 18

                                               = 71 cm.

∴     perimeter of a quadrilateral = 71cm
