Answer:
<h3>₹ 1290</h3>
Step-by-step explanation:
The total surface area of the room = 2(LW + WH + LH)
TSA = 2(9*5 + 9*6 + 5*6)
TSA = 2(45 + 54 + 30)
TSA = 2(129)
TSA = 258
Hence the total surface area of the room is 258m²
If 1m² = ₹ 5
258m² = 5(258) = ₹ 1290
The cost of white washing if the ceiling of the room is also whitewashed is ₹ 1290
Shoes= 10
Man= 5
Tie= 4
So, 10+5*4= 30 <— Answer
How to get variables:
Shoes:
3 shoes are equal to 30, so to find the value of the shoes use 3x=30. X=10
Man:
2 men and a shoe is equal to 20. So, 2x+10=20
2x=10
X=5
Tie:
2 ties and a man are 13. So,
2x+5=13
2x=8
X=4
