Question

The area of a rectangle is 108 m². If its length is 9 m, find its width and perimeter​

Answer 1

Answer:

The width of the rectangle is 12 m.

Step-by-step explanation:

The area of a rectangle is 108 m².

we know that,

         Length of the rectangle is given by 9 m.

             Area of a rectangle= length × Breadth

             $108=9 \cdot width\\ \\ width=\frac{108}{9}=12$            

Width of the rectangle is 12 m.                    

Answer 2

Answer:

The width and perimeter of the rectangle will be 12 m and 42 m respectively

Step by step explanation:

The area of a rectangle is given to be 108 m² and length is given to be 9 m

We have to find the width and perimeter

area of rectangle = length × width

108 = 9 × width

width = 108/9

width = 12 m

Perimeter the rectangle = 2 ( length + breadth )

= 2 ( 12 + 9 )

= 2 × 21

= 42 m
