in measuring the sides of a rectangle, one side is taken 4 % in excess, and the other 3 % in deficit. find the error percent in the area calculated from these measurements.  Pick:
A) 0.11 %
B) 0.7 %
C) 0.4 %
D) 0.6 %
E) 0.88 %

in measuring the sides of a rectangle, one side is taken 4 % in excess, and the other 3 % in deficit. find the error percent in the area calculated from these measurements.
subtract(subtract(4, 3), divide(multiply(4, 3), const_100))
"let x and y be the sides of the rectangle . then , correct area = xy . calculated area = ( 26 / 25 ) x ( 32 / 33 ) y = ( 344 / 341 ) ( xy ) error in measurement = ( 344 / 341 ) xy - xy = ( 3 / 341 ) xy error percentage = [ ( 3 / 341 ) xy ( 1 / xy ) 100 ] % = ( 22 / 25 ) % = 0.88 % . answer is e ."
