Answer:
126
Step-by-step explanation:
Let the total number of postcard with stamp on it =x
Out of 350 postcards, x has stamp on it.
Out of 75 postcards, 27 has stamp on it.
Expressing these as a ratio:
350:x=75:27
350/x=75/27
Cross multiply
75x=350*27
x=(350*27)/75
x= 126
Therefore, the the total number of postcards in the box with stamps on them is 126.

The answer for this question, to the correct significant digits, would
be 39 feet squared. This can be worked out in the following way: S=a*a
ft^2S=6.25*6.25S=39.0625?39.1 9and then round this up to find the answer
of 39 square feet)
