Question

# Find the breadth of a rectangle whose area is 144 m2 and length is 16 m. Also find its perimeter.

## The correct answer is: breadth of the given rectangle is 9 m & perimeter is 50 m.

### Hint:-

i. Area of a rectangle = length × breadth

ii. Perimeter of a rectangle = 2 (length + breadth)

Step-by-step solution:-

From the given information, length = 16 & Area = 144

Let the breadth be x m

i. Area of the given rectangle = length × breadth

∴ 144 = 16 × x

∴ 144 / 16 = x

∴ x = 9m .................................................. (Equation i)

ii. Perimeter of rectangle = 2 (length + breadth)

∴ Perimeter of rectangle = 2 (16 + 9) ............................................ (From Equation i)

∴ Perimeter of rectangle = 2 (25)

∴ Perimeter of rectangle = 50 m

Final Answer:-

∴ breadth of the given rectangle is 9 m & perimeter is 50 m.
