Question

please do it explanation form​

Answer 1

Step-by-step explanation:

since tri ABC~triPQR we get,AB/PQ=BC/QR=AC/PR----equation 1

so now,arABC/arPQR=CA/RP(from eq1) 81/121=9/RP 81RP=121*9

RP=121*9/81 RP=1089/81

RP=13.444cm

Answer 2

Answer:

11

Step-by-step explanation:

Since triangle ABC and PQR are similar

area of abc/ AD^2 = area of triangle POR/PM ^2

81/9^2= 121/PM^2

81/81=121/PM^2

PM= 11
