Now after the change Length = 85x, and width = 140 y. Area = 11900xy
% Change = (11900xy - 10000xy)/(10000xy) = 19 % Increase. Hence Final answer: (D). <hau> Bari tsawon T na rectangle ya zama 100x, kuma nisa ya zama 100y. Yankin = 100x * 100y = 10000xy Yanzu bayan canji Length = 85x, da kuma nisa = 140 y. Yankin = 11900xy % Canji = (11900xy - 10000xy) / ((10000xy) = Ƙara 19%. Saboda haka Amsar karshe: (D).
