Ishan wants to do

Answer :

let the length be x and breadth be y

For the first condition


(x - 50) (y + 50) = xy


50x – 50y = 2500


x – y = 50 …. (i)


For the second condition


(x - 10) (y - 20) = xy – 5300


2x + y = 550 …(ii)


Substituting these values in matric form



It is in the form of AX = B, then the solution matric is X = A - 1X



|A| = 1 + 2 = 3





Therefore, x = 200 and y = 150
