Camilla · Answer 1

The area of the frame is 180 cm squared

Step-by-step explanation:

Area of the painting

=length⋅width

=20⋅16

=320 cm squared

Area of the painting and frame

=length⋅width

=25⋅20

=500 cm squared

Let's subtract the area of the painting from the area of the painting and the frame to find the area of just the frame:

500 - 320 = 180 cm squared
