14. The area of a rectangle is 375 square inches and it’s perimeter is 80 inches. Find both the length and width.

Length   inches

Width inches

Step-by-step explanation:

Let = length of rectangle, = width of rectangle

Given the area and the perimeter of the rectangle, we can write:

So:

Now, we can use substitution to find the value of :

(Quadratic equation)

∴

We can use substitution again to find the value of

∵ Length usually refers to the longer side of a rectangle, ∴ length inches and width inches.

Hope this helps :)

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
