Answer:
A 20
Step-by-step explanation:
Given
Phone Battery Life (hours)
A 20
B 25
C 10
D 18
8.45% of the battery life of each mobile phone is used in a day by a typical user
Calculating Hours of battery life in a day for each mobile
A 20
Battery life for A = hours
B 25
Battery life for B = hours
C 10
Battery life for C = hours
D 18
Battery life for D = hours
Therefor Mobile phone A 20 uses a total of 1.69 hours of battery life in a day
58 should be the answer for the perimeter
5 using the Pythagorean theory
