1. Answer:

   35

   Step-by-step explanation:

   First change the length into cm.

   [1m= 100cm]

   7m= 700cm

   3m 85cm= 3×100+85= 385cm

   12m95cm= 12×100+95=1295cm

   Find the H.C.F of 3 lengths 700cm, 385cm, 1295cm

   700= 2× 2× 5×5×7 = 2²×5²×7

   385= 5×7×11

   1295= 5×7×37

   H.C.F= 5×7 = 35

   The longest tape which can be used to measure exactly the length 700cm, 385cm & 1295cm = 35
