A Triangle has an area of 36cm^2. The base and height are scaled by a factor of 5. What is the area of the resulting triangle?
Finger [1]

Answer:

Area of resulting triangle  will be 900 cm^2.

Step-by-step explanation:

When sides of  any polygon if scaled by a factor of k

then area is scaled by k^2

According to the above statement

therefore  here in the question since area of original triangle was 36cm^2

and both  base and height are scaled by a factor of 5.

therefore area of scaled triangle will be 5^2 times of the original

that is 25 x 36 which gives 900 cm^2

So area of resulting triangle will be 900 cm^2

Parking lot has 121 spots. Ratio of senior to junior is 7 to 4. How many spots go to each grade level?
Andrej [43]
I am going to build a chart this is best when using ratios 

              seniors    junior  total
                 7              4       
                 *?             *?     *?
    Totals                          121   

The way we fill out this chart is that we add the rows and multiply the columns. 

So we add 7 + 4 and fill it in our chart we get 11 

            seniors    junior  total
                 7              4       11
                 *?             *?     *?
    Totals                          121   

now to find the *? need to divide 121/11 to get *?

121/11 = 11

so now our chart looks like this 
            seniors    junior  total
                 7              4       11
                 11            11     11
    Totals                          121   

Now we multiply each column 

so
7 * 11  = 77
 4*11 = 44

now our chart look like this 

            seniors    junior  total
                 7              4       11
                 11            11     11
    Totals     77           44      121   

so seniors get 77 spaces 
and juniors get 44 spaces.
