A rectangle whose perimeter is 80 m has an area of 384 m^2. Find the dimensions of the rectangle.

Answers

Since area of a rectangle = length X width I came up with an answer of 16 X 24 =384
Also, 16+16+24+24 = 80

$2a+2b=80 \ /:2\ \ \ \Rightarrow\ \ \ \ a+b=40\ \ \ \Rightarrow\ \ \ a=40-b\n \na\cdot b=384\ \ \ \ \Rightarrow\ \ \ (40-b)\cdot b=384\ \ \ \ \Rightarrow\ \ \ -b^2+40b-384=0\n \n \Delta=40^2-4\cdot (-1)\cdot(-384)=1600-1536=64\ \ \ \Rightarrow\ \ \ √(\Delta) =8\n \nb_1= (-40-8)/(2\cdot(-1))= (-48)/(-2) =24\ \ \ \ \Rightarrow\ \ \ a_1=40-b_1=40-24=16 \n \nb_2= (-40+8)/(2\cdot(-1))= (-32)/(-2) =16\ \ \ \ \Rightarrow\ \ \ a_2=40-b_2=40-16=24$
