Question

The semiperimeter of an isosceles triangle whose equal sides are 14cm and other side is 12cm is ____ cm.

Answer 1

Answer:

20 cm

Step-by-step explanation:

semi Perimeter = (2 * equal sides + other side) ÷ 2

                          = (2 * 14 + 12) ÷ 2

                          = (28 + 12) ÷ 2

                           = 40 ÷ 2

                           = 20 cm
