Perimeter
2l + 2w = 27
l + w = 13.5

Area
l*w = 35

(35 / l) + l = 13.5
 35 + l^2 = 13.5l
l^2 - 13.5l + 35 = 0

Using this equation, we can find the length first
then width can be found

If 2 = 6, 3 =12, 4 = 20, 5 = 30, 6 = 42 then 9 = ?
Soloha48 [4]
At first you may get confused but look at those numbers carefully :)

as you see first result is divisible buy one of the product (second product in all cases is unknown)
so let's check where it will lead us :)

6/2=3

12/3=4

20/4=5

30/5=6

42/6=7

Now you can clearly see that every number was multiplied by number 1 higher than itself. 
2*(2+1)=6

3*(3+1)=12

4*(4+1)=20

etc...

it means that after equation sign there should be 90 because 

9*(9+1)=90 :)

Rene is going to the lake to visit some friends. If the lake is 60 miles away, and Rene is driving at 40 miles per hour the enti
Stels [109]
Distance at which the lake is located = 60 miles
Speed at which Rene traveled the entire distance = 40 miles per hour
We already know that
Speed = Distance/Time
Then
Time = Distance/speed
         = 60/40 hours
         = 3/2 hours          
         = (3/2) * 60 minutes
         = (3 * 30) minutes
         = 90 minutes
Rene will take 90 minutes to reach the lake.
