respectively. Find the breadth of the room.
​

Answer 1

Answer:

breadth is 18

Step-by-step explanation:

Answer 2

Area=280sq.m

length=22m

height=3.5m

$\begin{gathered}area = 2h(l + b) \\ 280 = 2(3.5)(22 + b) \\ 280 = 7(22 + b) \\ 280 \div 7 = 22 + b \\ 40 - 22 = b \\ b = 18m\end{gathered}$

b=18m

breath=18m
