Question

Find the perimeter of the triangles whose dimensions are given below.
(a) a = 4 cm, b = 5 cm, c = 6 cm (b) a = 8 cm, b = 11 cm, c = 13 cm
(c) a = 14 cm, b = 16 cm, c = 18 cm (d) a = 21 m, b = 23 m, c = 30 m​

Answer 1

Answer:

Perimeter of triangle = Sum of all sides

(a) Perimeter = a+b+c = 4+5+6 =15cm

(b) Perimeter = a+b+c = 8+11+13 = 32cm

(c) Perimeter =a+b+c = 14+16+18 = 48cm

(d) Perimeter = a+b+c = 21+23+30=74cm
