Question

hello.....


solve it....​

Answer 1

Answer:

Lateral surface area = 2 x height (length + wide)

perimeter = 2( length + width)

length + wide = 125

area costing of

lateral surface are painting = 15000/10=1500

m^2

height =1500/250=6 m

Answer 2

Answer:

$\huge{\bold{\red{Answer}}}}}$

Perimeter of rectangular floor of hall = 2 ( l + b )

2 ( l + b ) = 250

l + b = $\frac{250}{2}$

l + b = 125 m

Cost of painting the four walls at 10 per m square

= Rs 15000

Cost of painting the four walls at 1 per m square

= $\frac{15000}{10}$

= 1500 {m}^{2}

Lateral surface area = 2 ( l + b )h

= 2 × 125 × h = 1500

h = $\frac{1500}{2×125}$

h = 6 m
