The screen on the iPhone 11s has a base of 51.7mm and a height of
90.39mm. Find the area of the iPhone's screen. *
Your answer

4673 mm²

Step-by-step explanation:

Data

iPhone's screen is a rectangle. The area of rectangle is calculated as base*height. Replacing with data we get:

Area of rectangle = area of the iPhone's screen = 51.7 mm * 90.39 mm =  4673.163 mm² ≈ 4673 mm²

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

50-38=12
