Answer 1

Answer:

6m

Step-by-step explanation:

perimeter=2(l+b)=250

Area of four walls=15000/10sq.m=1500sq.m

Area of four walls=2(l+b)h

=250×h

250×h=1500

h=6m

Answer 2

Answer:

Height is 6 metres.

Step-by-step explanation:

Perimeter = 250

i.e. 2(l+b) = 250

i.e. (l+b) = 250/2

Thus, l+b= 125. (Remember, we will use it later)

Since, total cost of Painting = 15000 rs

and per metre square cost is 10rs.

Therefore, 15000/10 = 1500

Thus total area of four walls is 1500m²

Now area of four walls means Lateral Surface Area (LSA).

Formula of LSA = 2h(l+b)

now LSA = 1500

i.e. 2h(l+b) = 1500

2h x (125) = 1500

2h= 1500/125

2h = 12

thus, h= 6
