Answer:
Answer is C
Explanation:
It tells you on the graph paper that 1 square is 6 meters.
The problem says the Post Office is 60 meters long, in its longest dimension
The outine on the graph paper is 10 squares long on the longest side.
10 squares to represent 60 meters is 60 meters/10 squares = 6 meters per square
So we are shown in more than one way that a square on the graph paper represents a length of 6 meters.
Now, for the answers A,B,C, and D.
A is wrong because it says 6 squares for 1 meter. But it is actually the other way around, 6 meters for 1 square.
In B, C, and D they get the 6 meters /1 square part right. But these are proportions, where two fractions are stated to be equalt to each other. Which proportion is true?
There is an easy way to check!
IF a/b = c/d, for real, then ad = bc. (The product of the means equals the product of the extremes.) That is a rule in proportions, and is always mathematically true as long as there are no undefined terms (like zero in a denominator).
So if ad = bc, then B says that 360 = 10. False.
If ad = bc, then C says that 60 = 60. True.
If ad = bc, then D says that 360 = 10. false.
The answer is C
