Question

the base of an isosceles triangle is 4 by 3 cm the perimeter of the triangle is 4 integer 2 by 15 cm what is the length of the either of the remaining equal sides

Answer 1

Perimeter of isoceles triangle = 2a + b (where a is the length of equal sides)

4 2/15= 2a+4/3 = 62/15 = 2a+4/3

2a=42/15

a=21/15 = 7/5 cm

Therefore, length of equal sides= 7/5 cm = 1 2/5 cm
