Mark is painting the ceiling of a square room. If the area he paints is 400 sq. feet, what are the dimensions of the room?

20 by 20

Step-by-step explanation:

square root of 400 is 20

20 times 20 = 400

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

1/2*qr*rs
