Question

Please someone help me :( ​

Answer 1

Answer:

A: 16 times

B: 4.5 : 72

C: 12

Step-by-step explanation:

For part A, you multiple the base, which is three, by the height, which is also three. This gives you 9 then you divide that by 2 because it's a triangle. This gives you 4.5 as the area of triangle A. Next you divide 72 by 4.5 which gives you 16. 16 is the answer.

For part B, you just take the area of triangle A and the area of triangle B and put it down as a ratio.

For part C, You take 72 and times it by 2 because in a regular problem you would divide it by 2. This gives you 144. If you look at triangle A, you can see the base and height are the same length. This means the scaled triangle should be the same way. All you have to do is square root 144 which gives you the base and height, 12.
