Mpaghara = 11900xy % Mgbanwe = (11900xy - 10000xy) / ((10000xy) = 19% mmụba. N'ihi ya azịza ikpeazụ: (D). <eng> Let the length T of the rectangle be 100x, and width be 100y. Area = 100x * 100y = 10000xy
Now after the change Length = 85x, and width = 140 y. Area = 11900xy
% Change = (11900xy - 10000xy)/(10000xy) = 19 % Increase. Hence Final answer: (D).
