ㅤ

a. A triangle of sides 14 cm, 11 cm, 16 cm

Perimeter = 14+11+16= 41cm

ㅤ

b. An equilateral triangle of side 8 cm

Perimeter =8×3= 24cm

ㅤ

c. An Isosceles triangle with equal sides 6 cm each and third side 8 cm

Perimeter=2×6+8= 12+8= 20cm

Answer 2

Answer:

(a) perimeter of triangle of sides 14cm, 11cm, 16 cm = 14 + 11 + 16

= 41 cm

(b) perimeter of equilateral triangle of side 8cm = 8 +8+8 = 24cm

(c) perimeter of isosceles triangle with equal sides 6cm and unequal side 8cm = 6 +6+8 = 20 cm
