Question

find the perimeter of an isosceles triangle each of whose equal side measure 5.8 cm and the length of whose third side is 7.5 CM

Answer 1

Hey !!



First side = 5.8 cm.


Second side = 5.8 cm

And,

Third side = 7.5


Therefore,

Perimeter of triangle = 5.8 + 5.8 + 7.5 = 19.1 cm.

Answer 2

Perimeter of Isosceles triangle= Sum of all three sides.
Hence,
First side= 5.8 cm
Second Side= 5.8 cm [ In Isosceles triangle two sides are equal.]

Third Side= 7.5 cm [Given]

Now,

=> P = [5.8+5.8+7.5] cm
=> P = 19.1 cm
