First you take the area,
4 x 2 = 8 cm
Then you take 72 cm and divide it by 8 cm to get your length

Answer:
1.88
Step-by-step explanation:
2 meters is about six feet, the man is missing about 1.5 feet for his shadow. That means the elephant is also missing 1.5 feet. The elephant is 3 meters tall
3x - y = 6 ------------ (1)
y = x - 4 ------------ (2)
From (1) + (2) :
( 3x - y) + y = 6 + (x - 4)
3x - y + y = 6 + x - 4
3x = x + 2
2x = 2
x = 1 ------------- Sub into (2)
y = x - 4
y = 1 - 4
y = -3
Answer: x = 1, y = -3
