Question

The area of a square is 289 m2, find its perimeter?

hintHint:

find the length of the side of the square and then find the perimeter of the square by applying a general formula  .

The correct answer is: 68


    Ans :- 68
    Explanation :-
    Step 1:-
    Let the length of the square be a
    The area of square = (length of side)2  equals a squared
    Then, a squared equals 289 equals 17 squared not stretchy rightwards double arrow a equals 17 m
    Step 2:- find the perimeter of square by using length
    We find the perimeter of the square = 4a = 4 × 17 = 68m.
    The perimeter of square whose area is 289 (m2) is 68 m.
