 <translate> 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). <yor> Jẹ́ kí gígùn T ti onigun mẹ́rin náà jẹ 100x, àti gígùn jẹ 100y.
