A rectangular piece of paper has a width that is 3 inches less than its length. It is cut in half along a diagonal to create two
congruent right triangles with areas of 44 square inches. Which statements are true? Check all that apply.
The area of the rectangle is 88 square inches.
The equation x(x – 3) = 44 can be used to solve for the dimensions of the triangle.
The equation x2 – 3x – 88 = 0 can be used to solve for the length of the rectangle.
The triangle has a base of 11 inches and a height of 8 inches.
The rectangle has a width of 4 inches.

Answer:
Step-by-step explanation:
I have attached a written explanation to help :).
Let's say each side of the square =
If we put 7 squares in a row to make the rectangle,
length of the rectangle =
Area of a rectangle = length multiplied by width
Area of rectangle = multiplied by
=
We are also told that the total area = 567
So
Now solve for .
Divide both sides by 7.
Then square root both sides to find
= 9
