bonus:
tira is designing a rectangular room. she wants the room
to be 20 feet wide. what length must the room be if she
needs a perimeter of 60 feet?
a) write an equation for tira to find the length of the
room x. (remember, perimeter is the sum of all of the )
equation:
b) solve for the length of the room x.

60=2(20)+2x

x=10

Step-by-step explanation:

First, let's write some equations. I wrote 60=2(20)+2x, where x is the length of the room. To solve, first multiply 2 times 20 for 40 (60=40+2x). Then, I subtracted 40 from both sides (20=2x). Finally, I divided on both sides by 2 (10=x).

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
