Which is the best estimate of the area of a triangle that has a base of 24.62 cm and a height of 8.33 cm?

i reccomend the website mathpapa !

Step-by-step explanation:

Let Sister's age now = s  

So Larry is now s + 8  

In THREE Years Sister = s + 3  

Larry = {s + 8} + 3  

But We are told that he will be TWICE as old as Sister is NOW!!!  

So s + 11 = {2s}  

Solve s = 11  

So Sister is ELEVEN Years old and Larry is NINETEEN Years old.
