32 meters
Step-by-step explanation:
<u>The question is on scale</u>
Length of house on paper=100cm
Length of house actual=40m
<u>finding the scale used;</u>
make both lengths with similar units;
100cm rep 40m
100cm = 40×100 cm
100cm=4000cm
<em>1:40⇒1cm rep 40 cm</em>
<u>Finding actual measurement of the width</u>
1cm rep 40cm
80cm rep ?
cross multiply; (80×40)÷1= 3200cm
actual width=3200/100= 32 meters
When multiplying decimals, what you do with the decimal point is; C: line up the decimal points
<h3>How to Multiply Decimals?</h3>
A common way to multiply decimals is to treat them as whole numbers, and then position the decimal point in the product. The number of digits after the decimal points in the factors determines where the decimal point is placed in the answer. For example, 0.3 x 0.8 = 0.24.
Now, when multiplying decimals, the most important step is to line up the decimal points. Line up the decimal points so that similar place values are lined up. In other words, the tens place in both numbers should be lined up, the ones place in both numbers should be lined up as well and son.
Thus, option C is the correct answer.
