Question

a The breadth of a rectangular room is one third of its length. If the area of the room is 1200 m2. Find the length of the room. a) 60 m b) 65 m c) 66 m d) 67 m​

Answer 1

Answer:

The length of the room is ( a) 60 m

Step-by-step explanation:

Let us consider the length =x

The breadth of a rectangular room is one third of its length

and

          breadth=$\frac{x}{3}$

Area of the rectangle =Length ×Breadth

$1200=x \cdot \frac{x}{3} \\ \\ x^{2} =3600\\ \\ x=60$

Length =x=60
