Required Perimeter = AB + BC + CA
AB = sqrt((5 - (-1))^2 + (-1 - 1)^2) = sqrt(6^2 + (-2)^2) = sqrt(36 + 4) = sqrt(40) = 6.3
BC = sqrt((-1 - 0)^2 + (1 - (-3))^2) = sqrt((-1)^2 + 4^2) = sqrt(1 + 16) = sqrt(17) = 4.1
CA = sqrt((0 - 5)^2 + (-3 - (-1))^2) = sqrt((-5)^2 + (-2)^2) = sqrt(25 + 4) = sqrt(29) = 5.4
Perimeter = 6.3 + 4.1 + 5.4 = 15.8 units
Answer:
Multiplication (150x4=600 25x4=100%)
Answer: 20,000
Step-by-step explanation:
We can estimate the product of 5 and 4,257 by multiplying 5 by 4,000
5 * 4,000 = 20,000
The product of 5 and 4,257 is about 20,000
The real answer (not an estimate)
21,285
That is around 20,000 so we are correct
