* I will fan & medal! xoxo. * :D
The staff at the community center make a rectangular ice skating rink every year. They use 140 meters of boarding to enclose it. So the area of the rink depends upon the width undefined chooses. This rule describes how the area depends on the width, w:
w(70 ??? w) or 70w ??? w^2
Width  Area
10  600
15  825
20  1000
25  ?
The table shows some of the values for this function. Help complete the able. If the width is 25 metes, what will the area be?

Best ResponseYou've already chosen the best response.1Well, if you know that the width is 25 meters, then use: A=l•w You know that P=2(l+w) So you can use that to find the length. 140=2(l+25) solve for length

Best ResponseYou've already chosen the best response.1So find l, and then the Area

Best ResponseYou've already chosen the best response.1I don't have a calc. so lets do that.... 25•45= 25•(25+20)= 25•25+25•20= 625+500= 1125. Yes:)
