Answered

The perimeter (in m) of a square whose area is equal to the area of rectangle of length 13.6 m and breath 3.4 m is

- 18
- 20
- 27.2
- 17

Best answer

**Answer: (3) 27.2 m**

**Explanation:-**

The length of the rectangle = 13.6 m

The breadth of the rectangle = 3.4 m

**Formula-**

**The area of the rectangle = l x b **

Where, l – length of the rectangle, b – breadth of the rectangle.

Then, the area of rectangle = 13.6 x 3.4

= 46.26 sq. m.

The area of rectangle = the area of square ( according to the question)

**Formula-**

**The area of square = side x side**

Then, Side x side = 46.26

Side = 6.8 (square root of both side)

**Formula-**

**The perimeter of square = 4 x side**

= 4 x 6.8

= 27.2 m

Hence, the answer is (3) 27.2 m.
