<h2>Given :- </h2>
- wide of the hall (Breadth) = 10m
<h2>To Find :- </h2>
- Surface area of the walls (Four walls area)
<h2>Formula :- </h2>
Four walls area of the hall = 2h(l+b)
where,
<h2>Solution : - </h2>
By substituting values according to the formula,
➙ 2 × 4m(12m + 10m)
➙ 8m(22m)
➠ 176m²
It's option B
<h3><u>Hence, The surface area of the walls is (B) 176m²</u></h3>

Answer:
4.5
Step-by-step explanation:
Probably too late for your RSM homework, but here is the solution:
6/(9-x) [Time they motored upstream] +6/x [Time it took the bottle to get back to the starting point] = 8/3 [Total Time]
Simplify to 54/(x(9-x))=8/3
Cross multiply: 162=(8x)(9-x)
Simplify -x^2+9x=20.25
Multiply both sides by negative one and move 20.25 to the other side. x^2-9x+20.25=0
Solve and get 4.5 :D!
