The rectangular floor of colbys room is 9 feet long and 6 feet wide. What is the area of the floor

  54 ft^2

Step-by-step explanation:

The area is the product of length and width:

  A = LW = (9 ft)(6 ft)

  A = 54 ft^2

The area of the floor is 54 square feet.

area of the rectangular floor = 54 ft²

Step-by-step explanation:

The area of a rectangle is the product of the length and width. The floor is rectangular therefore the area of the floor can be calculated by using the area of a rectangle.

area of the rectangular floor = length × width

length = 9 ft

width = 6 ft

area of the rectangular floor = length × width

area of the rectangular floor = 9 × 6

area of the rectangular floor = 54 ft²

i believe the answer is c.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
