All rectangles are quadrilaterals because a quadrilateral has 4 sides and all rectangles have 4 sides so that one is correct
Answer:
15
Step-by-step explanation:
12/8 =1.5 * 10 =15
Answer:
It is three times as large
Step-by-step explanation:
If a ration is also a fraction, and your wording is correct than an enlargement of 1:3 where 1 is the original shape would suggest that the 3 would be that same original shape, be enlarged in terms of 3 compares to 1 so a 300% enlargement.
if the original rectangle has a 16 cm perimeter, than the new rectangle has a 48 cm perimeter.
The correct answer is C. 4.
Typically, we look to multiply by the bottom number (the denominator) in order to get fractions to cancel out. If we multiply 1/6 by 6, we get just 1, which is why we do it.
In this problem, you have two different denominators, 2 and 4. If you multiply them all by 2, the term -3/4m will still be a fraction.
-3/4m * 2 = -3/2m
As a result, we must try 4 instead. This causes all of them to cease being a fraction. Even the one with 2 as a denominator.
-1/2 * 4 = -2
The area of a shape is the amount of space it can occupy.
<em>The surface area of the larger prism is 4 times the surface area of the smaller prism.
</em>
<em />
<em />
<em>Let the dimension of one side of the smaller prism be: l and w</em>
<em>Let the dimension of one side of the bigger prism be: L and W</em>
<em />
So, we have:


The area of these corresponding sides are:
---- the first

While, the area of the second is:


The ratio of these two sides are:

<em>This gives</em>

Cancel out common terms

Express as fractions

Also, we have:

This gives

Cross multiply


Hence, option (c) is true
