Let `R` be set of points inside a rectangle of sides `a` and `b` `(a, b > 1)` with two sides along the positive direction of x-axis and y-axis

Options

A. `R = {(x, y) : 0 le x le a, 0 le y le b}`
B. `R = {(x,y) : 0 le x lt a, 0 le y le b}`
C. `R = {(x,y): 0 le x le a, 0 lt y lt b}`
D. `R = {(x,y): 0 lt x lt a, 0 lt y lt b}`

Answer

D

Explanation

Since, R be the set of points inside the rectangle.
`:. R = {(x, y) : 0 lt x lt a` a nd `0 lt y lt b}`
