Reasoning The diagram shows a rug laid on a wooden floor. Its width is 2 m less than the width of the room.
a Write an equation to represent the width of
the room (y).
b Write an equation to represent the area of
the rug, which is 3 m?.
< Use these two equations to find the value of x
and hence the width of the room (y).
Rug
2x + 1
(y)

what is the original number? you forgot to add it.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
