$\huge\underline\orange{\sf CorrectQuestion :-}$

★ The area of four walls of a hall is 266 sq.m and the Length and Breadth of the hall is 12 m and 7 m respectively. Find the Height of the wall ★

Given:

• Area of hall is 266 m²
• Length of four walls of hall is 12 m
• Breadth of four walls of hall is 7 m

To Find:

• Height of the hall

Solution: Let the Height of the hall be h m

★ We know that Area of four walls of a room = 2 ( Length + Breadth) Height ★

$\small\implies{\sf }$ 266m² = 2 ( 12 + 7 ) h

$\small\implies{\sf }$ 266m² = 2 ( 19)h

$\small\implies{\sf }$ 266 = 38h

$\small\implies{\sf }$ 266/38 = h

$\small\implies{\sf }$ 7m = Height

Hence, The Height of the wall is h = 7 m
