Question

Find the perimeter of triangle 7m 28 cm, 10cm 59m,13m 66cm

Answer 1

Perimeter = sum of all sides

                 ==> 7 m 28 cm + 10 m 59 cm + 13 m 66 cm

We know that 1 m = 100 cm

                 ==>  ( 7×100 + 28 + 10×100  + 59  + 13×100 + 66 ) cm

                 ==> 700 cm + 28 cm + 1000 cm + 59 cm + 1300 cm + 66 cm

                 ==>  3153 cm

The perimeter is 3153 cm or 31.53 m

Hope it helps
