the answer is 228

Question

A=LW=240x120-28,800inches

28,800 divided by 100=288

Answer 1

the area of a rectangle 240 by 120 is the same as the area of a rectangle 288 by 100

240x120 = 28800 = A = LW

288x100 =28800 = A = L'W'

increase L by 48 and decrease W by 20 and the area remains the same

120x5/6 = 100

240x6/5 = 288

increase length by a factor of J, and decrease the width by a factor of 1/J, and the area stays the same

double L from 240 to 480

and half W from 120 to 60

480x60 = 28800
