is an equation can be used to calculate the area (a)
Explanation:
Here, l is the length of a rectangle and w is the width of the room..
As per the statement:
area of a rectangle can be calculated by multiplying the width (w) of the room by the length (I) of the room..
Since, room is in the shape of rectangle.
Area of a rectangle(a) is multiplying the width (w) of the room by the length (I) of the room
⇒

Therefore, an equation can be used to calculate the area (a) is,
