I have a square piece of paper.
Square has all equal sides (each side was 10 cm and there were 4 sides)
I fold square A in half to make rectangle B.
I fold rectangle B in half to make square C.
a) what is the perimeter of rectangle B?
b) what is the perimeter of square C?
Answer and I'll give you brainiest :)

a) 30 cm

b) 20 cm

Step-by-step explanation:

Rectangle B's perimeter is 10+10+5+5 which is 30

Square C's perimeter is 5+5+5+5 which is 20

d is correct

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
