Question

What is the area of the grey matting in this 16” by 20” picture frame if the picture to be framed is 8” x 10”?

Picture frame.



Select one:
a. 320 sq. in.
b. 80 sq. in. Incorrect
c. 240 sq. in.
d. 480 sq. in.

Answer 1

240 sq. in.

Explanation:

A 16x20 inch picture frame has an area of (16)(20)=320sq. in. An 8x10 inch picture to be framed has (8)(10)=80sq. in. The remaining area is 320-80 = 240sq. in.

Answer 2

c. 240 sq. in.

Explanation:

area = length x width

find the area of 16 x 20 and 8x10, then subtract the 8x10 area from the 16 x 20.

16 x 20 = 320

8 x 10 = 80

320 - 80 = 240
