Question

If the length and breadth of a room are $15m$ and $10m$ respectively, then

Breadth : Area $=$________ $\left[1:5/1:15\right]$

Answer 1

Given that,

Length of the room $=15m$

Breadth of the room $=10m$

Area of the room $=15\times 10=150m^2$

Now, ratio of breadth to the area of the room $=10:150$

Lowest form of $10:150=\frac{10}{150}=\frac{1}{15}=1:15$ ( Divide both $10$ and $150$ by their HCF $10$)

Hence, Breadth : Area $=$$1:15$
