Question

the floor of a rectangular hall has a perimeter 300m and it's height is 5m then find the lateral surface area of the hall. plz urgent

Answer 1

________________________

★ Solution :-

Given,

• Perimeter of the hall = 300 m
• Height of hall = 8m

We need to find ,

• Lateral surface area of hall = ?

As we know that

Perimeter = 2 ( length + breadth )

Substituting the value of perimeter

⇒ 300 = 2( l + b)

⇒ 300 ÷ 2 = l + b

⇒ l + b = 150 m ………. equation ( 1 )

Now , finding lateral surface area ( LSA )

LSA of cuboid = 2h × ( l + b )

Substituting the known values we have ,

➵ LSA = 2(8) × [ 150 ]

[ ∵ Equation 1 ]

➵ LSA = 16 × 150

➵ LSA = 2400 m²

Hence , lateral surface area of the hall = 2400m²
