Answer 1

Answer:180cm²

Step-by-step explanation:

First you find the area of just the painting so multiply 20 x 16 which = 320

Then, you find the area of the whole thing by multiplying 20 x 25 which = 500

The area of a rectangle is given by the formula

A = l * w, where l is the length of the rectangle and w is the width.

The area of the framed picture is given by

A = 25(20) = 500 cm².

The area of just the painting is given by

A = 16(20) = 320 cm²

This means the area of just the frame is given by

500-320 = 180 cm²
