Answer:

Step-by-step explanation:

first find area of photo i.e. 20 × 15 which is equal to 300

then find the area of wooden frame i.e. 30 × 45 which is equal to 1350

now subtract the area of photo from the area of wooden frame i.e. 1350 - 300 which is equal to 1050

now square root of 1050 is equal to 32.40
