Question

You are choosing a new cell phone. The screen on your current phone is 10.8 cm high and 6.1 cm wide. The screen on the new phone is 12.4 cm high by 6.9 cm wide. How much larger is the area of the new screened in the area of the old screen?

Answer 1

Answer:

19.68 cm^2

Step-by-step explanation:

Area of Current Phone

First, find the area of the current phone. We can assume the screen is rectangular. The area of a rectangle can be found using:

a=l*w

We know the length is 10.8, and the width is 6.1, so we can substitute them in

a=10.8*6.1

a=65.88

Current Phone: 65.88 cm^2

Area of New Phone

Find the area of the new phone.

a=l*w

We know the length is 12.4, and the width is 6.9, so we can substitute them in

a=12.4*6.9

a=85.56

New Phone: 85.56 cm^2

Difference

We want to find how much larger the new phone screen is. To do this, find the difference between the new phone area, and the current phone area.

new phone - current phone

85.56-65.88

19.68

The new phone screen is 19.68 cm^2 larger than the current phone screen

Answer 2

Answer:

the area of the new phone would be 19.68cm larger than your old phone.

Step-by-step explanation:

we know that when you multiply the two lengths of your old phone will give you the area of 65.88cm. (10.8x6.1=65.88)

and we know that the area of the new phone would have an area of 85.6cm (12.4x6.9=85.6)

and now we have to subtract the area of the old phone from the area of the new phone which gives us the answer of 19.68cm larger than the old phone . (85.6-65.8=19.68)

i hope this helped! have a great day.
