Difficulty: Easy
Correct Answer: 62
Explanation:
Introduction / Context:
For a rectangle with length L and breadth W, the diagonal d satisfies d^2 = L^2 + W^2. From L, W we obtain the perimeter P = 2(L + W). Here d and W are given, so L follows from Pythagoras.
Given Data / Assumptions:
Concept / Approach:
Compute L = √(d^2 − W^2) and then P = 2(L + W).
Step-by-Step Solution:
Verification / Alternative check:
Check the triple: 7, 24, 25 is a classic Pythagorean triple. Hence computations are consistent.
Why Other Options Are Wrong:
124 and 82 are double-counting or mixing values; 41 is half of 82 and not a valid perimeter given L and W.
Final Answer:
62
