Let R be set of points inside a rectangle of sides a and b (a, b > 1)

1.	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. ThenA. R = {(x, y) : 0 ≤ x ≤ a, 0 ≤ y ≤ b}B. R = {(x, y) : 0 ≤ x < a, 0 ≤ y ≤ b}C. R = {(x, y) : 0 ≤ x ≤ a, 0 < y < b}D. R = {(x, y) : 0 < x < a, 0 < y < b}
Answer» D. R = {(x, y) : 0 < x < a, 0 < y < b} Given: R be set of points inside a rectangle of sides a and b Since, a, b > 1 a and b cannot be equal to 0 Therefore, R = {(x, y) : 0 < x < a, 0 < y < b}

Answer»

D. R = {(x, y) : 0 < x < a, 0 < y < b}

Given: R be set of points inside a rectangle of sides a and b

Since, a, b > 1

a and b cannot be equal to 0

Therefore, R = {(x, y) : 0 < x < a, 0 < y < b}
