A student 5

A student took the measurements of his classroom and gave the width as 7m and the length as 9m. If there is an error of 2 percent in measurement, determine the greatest value of [X+Y]/X if X and Y are the width and length of the classroom, respectively. Give your answer to 4 decimal places.

Correct answer:

w =  2.3319

Step-by-step explanation:

a=7 m b=9 m  e=2%=1002=501=0.02  e1=1+e/2=1+0.02/2=100101=11001=1.01 e2=1e/2=10.02/2=10099=0.99  w0=aa+b=77+9=716=2722.2857 w=a e2a e1+b e1=7 0.997 1.01+9 1.01=2.3319
