Answer:
19.68 cm^2
Step-by-step explanation:
<em>Area of Current Phone </em>
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
<em>Area of New Phone </em>
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
<em>Difference </em>
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
<em><u>The new phone screen is 19.68 cm^2 larger than the current phone screen</u></em>
