Answer 2

Sᴏʟᴜᴛɪᴏɴ :-

Let us assume that breadth of room is = x m.

Than,

→ Length = double of its breadth = 2 * x = 2x m.

And, given That,

→ Height of room = 4.5 m.

→ volume of room = 225 m³.

So, comparing their volume with formula , we get,

→ Volume of room = Length * Breadth * Height

→ 2x * x * 4.5 = 225

→ 9x² = 225

→ x² = 25

→ x = 5.

Hence,

→ Breadth of room = x = 5m. (Ans.)

→ Length of Room = 2x = 2*5 = 10m. (Ans.)
