Question

perimeter of an isosceles triangle is 40 cm and one of the equal side is 18 cm find the smallest side of the triangle​

Answer 1

Answer: 4 cm

Step-by-step explanation:. Isosceles triangle has two equal sides. Since one is given as 18, the total sum of these two sides will be 18 x 2 = 36.

Therefore, the smaller side = 40 - 36 = 4 cm.
