A house and lot are appraised 312,000. If the value of the house is three times the value of the lot, how much is the house worth?

936000

Step-by-step explanation:

lot= x, house = 3 times of lot = 3 × x = 3x

x= 312000 so 3x =3× 312000=936000

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
