Pls answer the 12th Q

Answer»

Answer:

In an isosceles triangle 2 SIDES are EQUAL so

Side 1 = 4 \frac{3}{4}

Side 2 = 4 \frac{3}{4}

Side 3 must be =  PERIMETER - (Side 1 + Side 2)

                         =  20 -  (4\frac{3}{4} + 4\frac{3}{4})

                         = 20 - 9.5

                         = 10.5

Hence Side 3 = 10.5 cm

Hope it helps
