The area of a rectangular room is 238 square feet. The width is 3 feet less than the length. What are the dimensions?

rectangular area = width * length = 238 ft²

width = length - 3

consider length = x

width = x -3

238 = x *(x-3)

238 = x²-3x

x²-3x-238=0

(x-17)(x+14)

x = - 14 we dont use it because dimensions cant be negative

x = 17

length = 17 ft

width = 14 ft

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
