If each side of a rectangle is increased by 50% with the length being double the width, find the percentage change in its area?
Answers.
A) 284%	B) 276%	C) 265.25%	D) 284.5%	E) 275%
area = 2a x a   New length = 250a / 100 = 5a /2   New width = 150a / 100 = 3a /2   New area =(5a x 3a) / (2 x 2) = (15a²/4)   increased area== (15a²/4) - a²   Increase %= [(11a²/4 ) x (1/a² ) x 100]% = 275%   answer :275%
