The answer in the 1st question is 15 in wide.
first to see what we need to multiply the 3 by we need to multiply 3.5, 3.5 x 5 = 17.5
so we know we need to multiply 3 by 5 which is 15 in wide
The answer in the 2nd question is 4 ft x 6
Every 0.5 cm is 6 inches = 1 cm is 1 ft
since the drawing is 6 cm wide the flag will be 6 ft wide
since the drawing is 4 cm long it is 4 ft long
