Question

In the given Fig. all triangles are equilateral and AB = 8 units. Other triangles have

been formed by taking the mid points of the sides. What is the perimeter of the

figure?​

Answer 1

Answer:

70 cm is the perimeter of the total figure

Answer 2

Answer:

66 unit

Explanation=

Triangle ABC = 8x3

= 24 unit

layer 1 of tri.= 8÷2 ( because 'Other triangles have

been formed by taking the mid points of the sides.')

= 4

Perimeter = (4x3)x3) -12 (because one side is connected with tri ABC, hence 4x3)

=24unit

Layer 2 of tri. = 4 ÷ 2 per side

perimeter= (2×3)×3)-6

=12 unit

layer 3 of tri.= 2÷2

perimeter= (1×3)×3) - 3

= 6unit

TOTAL PERIMETER= 24+24+12+6

=66 unit

Thank you. Hope it is well explained
