Step-by-step explanation:
I know it's not a 3 digit number, but it's impossible to make a 3 digit number in your specifications.
<u>ANSWER:</u>
The bare canvas is of 17 cm length.
<u>SOLUTION:</u>
Given, a square-shaped canvas painting was enlarged by adding a 4-centimeter wide decorative frame to the length and width of the canvas.
The area of the framed painting is 625
,
Let, the length of the bare paintings be x.
Then, after adding the frame,
length becomes x + 4 + 4 = x + 8. [we added 4 two times, because frame adds on both sides of painting.]
Now, we are given that, area of the framed painting is 625 
Area = 625
= 625
= 
x + 8 = 25
x = 25 – 8 = 17
Hence, the bare canvas is of 17 cm length.
The answer is A) x = 9
We know this because every four sided figure has angles that measure up to 360. So we can subtract all of the angles and then use the remaining angle to solve the problem.
360 - 90 - 90 - 99 = 81.
So with the remaining angle being 81, we can solve for x.
x^2 = 81
x = +/-9
Since +9 is the only answer that makes sense in this case, x = 9.
