Question

if t
wo equal sides of an isosceles triangle are 5x -2 and 4x + 2 and third side is 2x - 1 find the perimeter
​

Answer 1

A/Q =》 5x-2 = 4x +2

=》 5x- 4x = 2+2

=》 x = 4

Sides = 5x-2 = 5×4-2= 18 cm

= 4x + 2 = 4×4+2 = 18 cm

= 2x-1 = 2×4-1 = 7 cm

perimeter of triangle = 18+ 18+7 = 43 cm
