The water will last for 3 days
<em><u>Solution:</u></em>
Given that, village having a population of 4000, requires 150 litres of water per head per day
<em><u>Let us first find the volume of tank</u></em>
The tank measuring 20m x 15m x 6m
Length = 20 m
Breadth = 15 m
Height = 6 m


Thus volume of tank is 1800 cubic meter
From given,
Water required per person per day = 150 liters
<em><u>Therefore, water required for 4000 people per day is:</u></em>

Convert to meters

<em><u>How many days will the water of this tank last?</u></em>


Thus the water will last for 3 days

Answer:
The height of triangle EFG is 9 units
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the area of a square ABCD
The area of a square is equal to

where
b is the length side of the square
we have

substitute

step 2
Find the height of triangle EFG
The area of triangle EFG is equal to

where
b is the base of triangle
h is the height of triangle
we have

---> area of triangle EFG is the same that the area of square ABCD
substitute the given values in the formula

solve for h

therefore
The height of triangle EFG is 9 units
