Answer 1

i hope it will help you

Answer 2

The dimension are 770 cm , 429 cm and 385 cm
For the tape to be of longest possible length we need to find the HCF of 770 ,429 and 385
770 = 2×5×7×11
429 = 3×11×13
385 = 5×7×11
HCF =11
Therefore, the length of the longest tape which can measure the three dimensions of the room exactly is 11 cm
