Best ResponseYou've already chosen the best response.0\(P=2(l+w)\) or \(P=2l + 2w\)

Best ResponseYou've already chosen the best response.0Just plug in the numbers. Perimeter= 53 and width=11. Then find the length (\(l\)).

Best ResponseYou've already chosen the best response.0Once you've found the length, use the formula in getting the area of a rectangle. \[\huge A=l \times w\]

Best ResponseYou've already chosen the best response.0And the perimeter is 53.

Best ResponseYou've already chosen the best response.0I did 53= 2L + 2(11)

Best ResponseYou've already chosen the best response.0So it's now...\[53=2l+22\]

Best ResponseYou've already chosen the best response.0You subtract 22 on both sides. What did you get?

Best ResponseYou've already chosen the best response.0The figure above shows the rectangle and the perimeter. 2 sides measure 11 cm each. The entire perimeter measures 53 cm.

Best ResponseYou've already chosen the best response.0The perimeter minus the two known sides is the same as the two unknown sides. 53 cm  22 cm = 31 cm Since 31 cm is the length of two sides, each side measures 31 cm / 2 = 15.5 cm

Best ResponseYou've already chosen the best response.0I waited until you wrote this. This pretty much is the side. dw:1439245350104:dw

Best ResponseYou've already chosen the best response.0@Halia Don't worry. I got you. What is the length first?

anonymous

Best ResponseYou've already chosen the best response.0I got 15 for the length @mathway

anonymous

Best ResponseYou've already chosen the best response.0Partly correct, but is that the exact length? The length has a decimal. :)

Best ResponseYou've already chosen the best response.0And now, for the area (finally!!!), multiply the length and width.
