Answer 2

Answer:

18 m

Step-by-step explanation:

Given,

The length of the wall = 27m

The cost of whitewashing a wall per

${m}^{2}$ = rs 25

The total cost of whitewashing a wall = rs 12,150

Area of the wall = 12150÷ 25

= ${486m}^{2}$

We know that,

Area of the rectangle = l×b

${486m}^{2} = 27 \times b$

${486m}^{2} \div 27 = b$

$18 m= b$
