Question

The perimeter of an isosceles triangle is 10 ¾ cm . If one of its equal side is 2 ¾ cm ,the third side IS, 5 ¼ 5 ½ 5 ¾ None of these

Answer 1

Answer:

The perimeter of an isosceles triangle is 10–3/4 or 43/4 cm.

If one of its equal sides is 2–5/6 or 17/6 cm,

then the third side will be 43/4 -34/6 = (258–136)/24

= 122/24

= 5–1/12 cm.
