A circle touches all four sides of a quadrilateral PQRS. If PQ = 11 cm, QR = 12 cm and PS = 8 cm, then what is the length of RS? |
9 cm 7.3 cm 7 cm 15 cm |
9 cm |
We know that, If a circle touches all four sides of quadrilateral PQRS then, PQ + RS = SP + RQ So, according to the question, = 11 + RS = 8 + 12 = RS = 20 - 11 = RS = 9 |
