Question

The ratio of the equal to unequal sides of an isosceles triangle is 3 : 4. If perimeter is 35cm , then the sides are

Answer 1

Answer:

Let the sides ve equal to x

Therefore the ratio be 3x;4x

Perimeter = 35

Therefore

Perimeter of triangle = |sum of all sides

35 = 3x + 3x + 4x

35 = 6x + 4x

35 = 10x

X = 3.5

Therefore the equal sides be = 3.5×3 = 10.5

And unequal side be = 4×3.5 = 15cm
