Question

Ava's smartphone is 15 cm and 8 wide. The screen is 12.5 cm long and 7 wide. If the entire phone's area was converted into a screen, how much additional area will be available to use?

Answer 1

Answer:

32.5 sq.cm

Step-by-step explanation:

There are 5 steps in this question:-

1/5. Let's subtract the area of the screen from the area of the phone to find how much more area will be available if the entire phone area is converted into a screen.

2/5. Phone area

Phone length= 15 cm

Phone breadth= 8 cm

Phone area= 15 cm x 8 cm = 120 sq.cm

3/5. Screen Area

Screen length= 12.5 cm

Screen breadth= 7 cm

Screen area = 12.5 cm x 7 cm = 87.5 sq.cm

4/5. Extra Area = (120 - 87.5) sq.cm

5/5. If the entire phone's area was converted into a screen, an additional area of 32.5 sq. cm will be available to use.
