Question

The area of a rectangle is 21 - 9x + 10. If its breadth is r-21 then find its length.​

Answer 1

Step by step explanation

$length \times \: breadth$

Let length be l

$l \times (x - 2) = \: {2x}^{2} - 9x + 10$

$l = \frac{ {(2x} ^ {2} - 9x + 10)}{(x - 2)}$

$l = (2x - 5)$

length = 2x-5

Answer 2

Step-by-step explanation:

l×(x−2)=2x2−9x+10

l = \frac{ {(2x} ^ {2} - 9x + 10)}{(x - 2)}l=(x−2)

(2x2−9x+10)

l = (2x - 5)l=(2x−5)

length = 2x-5
