The length and width of the rectangle could be (x-9) and (x-8).

Step-by-step explanation:

Since we have given that

Area of rectangle = x^2-17x+72

We need to find the length and width of the rectangle.

As we know the formula for "Area":

$Area=Length\times breadth\\$

Now, we first split the middle term:

$x^2-17x+72\\\\=x^2-9x-8x+72\\\\=x(x-9)-8(x-9)\\\\=(x-9)(x-8)$

Hence, the length and width of the rectangle could be (x-9) and (x-8).

X2 - 17x + 72

=(x - 9)(x - 8)

if x = 20 the length of the rectangle is 12 units and width 11 units.

Use trig

Step-by-step explanation:

sin(55) = x/21

x = 21sin(55)

use calculator in degree mode

cos(55) = y/21

21cos(55) = y
