Solution


Given:
    • An xy-coordinate plane

To find:
    • The value of a + b + c + d

Approach and Working:
    • b = 90 – 35 = 55
    • a = c = 90
    • d + c + 35 = 180
      o Implies, d = 180 – 125 = 55

Therefore, a + b + c + d = 90 + 55 + 90 + 55 = 290

Hence, the correct answer is Option D

Answer: D
