You trimmed a large square picture so that you could fit it into a frame. The area of the cut picture is 20 square inches. What is the area of the original picture?

100in^2

To find the area of the original picture, we need to consider the relationship between the cut picture and the original picture.

Let's assume that the original picture is a perfect square with side length "x" inches.

The original picture can be represented by x*x, which is the formula for the area of a square.

Now, the trimmed picture is a smaller square, but we don't know its side length. Let's represent its side length as "y" inches.

Since we're given that the area of the cut picture is 20 square inches, we can write the equation y*y = 20.

To find the area of the original picture, we need to solve for x*x.

Since y*y = 20, we can take the square root of both sides of the equation to find y.

√(y*y) = √20

Simplifying, we have y = √20.

Now, we can substitute the value of y into the formula for the area of the original picture:

x*x = (√20)*(√20)

Simplifying, we have x*x = 20.

Therefore, the area of the original picture is 20 square inches.

Missing info, perhaps width of frame

well, if the frame is 1x20, I guess the original picture was 400 in^2
