# What will be the Width of the Rectangle? If

The area of a rectangle with a side 144 m long is the same as that of a square having a side 84 m long. The width of the rectangle is:

- 7 cm
- 14 cm
- 49 cm
- Can’t be determined

**Answer: (3) 49 m**

**Explanation:-**

Let the width of the rectangle = X m

The side of a square = 84 m

**Formula-**

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

Then the area of the square = 84 x 84

= 7056

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

Then, 144 x X = 7056 (length of the rectangle = 144, Given in the question)

X = 7056/144

X = 49 m

Hence, the width of the rectangle is 49 m.
