Answer 1

Answer:

360cm sq.

Step-by-step explanation:

1- first we will find the area of the painting

30cmx24cm=720cm sq.

2- then we will find the area of larger painting after adding margin

length =30+(3+3)

=36

breath =24+(3+3)

=30

area=36cmx30cm

=1080cm sq.

3- then we will find the area of margin by subtracting the the smaller area from the largest area

=1080cm sq. -720cm sq.

=360cm sq.

Answer 2

360 sq. cm it's correct answer
