Step-by-step explanation:
perimeter=2(l+b)
18=2[(x+2)+x]
18=2(x+x+2)
18=2(2x+2)
18=4x+4
collecting like terms
18+4=4x
22=4x
dividing by 4
22/4=x
5²/4=5½
You just count the number of squares on the side, and you Pythagorean Theorem for the hypotenuse.
9 + 12 + (square root of 81 +144)
9 + 12 + 15
It’s 36
Solution: answer to a problem
No, because a translation is just a slide. For the orientation to change, the shape would have to be rotated or flipped.
