Faster method... Use the form x²-(s1+s2)x+(s1s2)=0 Where s1+s2= sum of roots and s1s2= product of roots (area of rectangle) Since the Perimeter is twice the sum of roots (i.e. 44), then s1+s2= 22 By substitution from the equation above, we get x²-22x+72=0 Finally, by factoring, we get (x-18)(x-4) The dimensions are L= 18 in² W= 4 in²

oh my god thank you I had no idea why he added 72 instead of subtracted or brought the negative to the 22 instead but it doesn't matter this rly is so much easier

The perimeter and the area of a rectangular play ground are 80cm and 384cm square respectively .. Find the length and breadth of the playground.., Answer : ?

[@alster724]

Let's use the root form of a quadratic equation x²-(s1+s2)x+(s1s2)=0 Where s1+s2 is the sum of roots and s1s2 is the product. The sum of roots is half the perimeter of 80 cm. So, s1+s2= 40 cm. s1s2 is the area which turns out to be 384 cm². Substituting these to the quadratic root form, we get x²-40x+384=0 Then by factoring (x-16)(x-24) Length = 24 cm. Breadth = 16 cm.
