Question

perimeter of an isosceles triangle is 43 CM base is 1 cm longer than the equal sign determine the length of equal side and the base

Answer 1

Let equal sides be x.

Hence base (unequal side) = x+1

Since Perimeter of triangle = Sum of all sides

=) 43cm = x + x + x+1

=) 43cm - 1 = 3x

=) 42cm = 3x

=) 42/3 = x

=) 14cm = x.

Hence equal sides is 14cm and base is 14+1cm
= 15cm.
