Answer:
Step-by-step explanation:
If the side lengths of the rectangle are 3 and 12, then the area, length times width, is 36.
If the area of the square is equivalent to the area of the rectangle, then
which is the formula for the area of a square. Take the square root of 36 to get that each side of the square is 6 inches long.
Since a square has 4 sides, we get that the perimeter of that square is 4 * 6 which is 24 inches.
Answer:
Step-by-step explanation:
The areas of four regions are given. We can simply add them to find the sum. To express them as a product, we need to look at common factors.
<h3>Sum</h3>The total of the given area expressions is ...
3x² +2x -6x -4 = 3x² -4x -4 . . . . sum
<h3>Product</h3>Extending the table to show common factors of each row and column, we have ...
Since each cell of the table is the product of the corresponding common factors, we can write the area as the product ...
(x -2)(3x +2) . . . . product
