find the height of the room 10 m long and 5m
wide , the area whose floor and celling together
is equal to the area of the 4 walls.

hint. ans=3.33m

answer:

well if the length and width is 10 by 5 it would be fifty for a wall but there is for so it should be 50 for each wall

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
