Answer:
The area of the enlarged triangle is 
times the original area
Step-by-step explanation:
we know that
The scale factor is equal to divide the measurement of the length side of the enlarged triangle by the the measurement of the length of the corresponding side of the original triangle
In his problem
Let
x------> the length side of the original triangle
so
2x-----> is the length of the corresponding side of the enlarged triangle
-------> that means is increasing
The scale factor squared is equal to the ratio of the area of the enlarged triangle divided by the area of the original triangle
so
Let
m-------> the area of the enlarged triangle
n------> the area of the original triangle
r-------> scale factor
we have
substitute
therefore
The area of the enlarged triangle is times the original area
Answer:
the final answer will be:
6x^3 -9
The complete question is
"A 4 inch by 6 inch picture is placed in a frame that creates a uniform border of x inches around the picture. The area of the entire frame (including where the picture is placed) is equal to 55.25 square inches.
What will be the width and length of the frame?"
The width of the frame is 4+2x, and the length of the frame is 6+2x.
<h3>What is the area of the rectangle?</h3>
The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
We know that the picture is 4 inches wide and 6 inches long.
Since there is a uniform border of x inches around the picture, so we must add 2x inches to each dimension.
The area will be = (4+2x)(6+2x) = 55.25
Therefore, the width of the frame is 4+2x, and the length of the frame is 6+2x.
