An engineering college has different buildings for different departments. ECE, 18 m from IT. is in the north. 20 m from EEE, ECE. is in the east. Civil, 30 m from IT. It is in the North West. Mechanical, Civil to 32 m. is to the south which is to the west of ECE. What is the minimum distance between Mechanical and ECE? MCQ with Answer and Explanation

Let IT be (0,0) and ECE be (0,18). Civil is 30m from IT in the NW. Mechanical is West of ECE, meaning its y-coordinate is 18. This aligns horizontally. Civil is 32m North of Mechanical or fits into a standard 18-24-30 right triangle (where base is 24m, height 18m, hypotenuse 30m). Thus, the distance along the horizontal axis mapping to Mechanical is 24m.
