A rectangular room has an area of 131 1/4 square feet. The length of the room is 12 1/2 feet. What is the width, in feet, of the room? (*HINT:THE ANSWER IS NOT B*)

A) 16411 feet
B) 118 3/4 feet
C) 10 1/2 feet
D) 25 feet

Step-by-step explanation:

C because when you multiply 10.5 x 12.5 that would equal 134.25 which is equivalent to 131 1/4

C

Step-by-step explanation:

The Answer is C because we are going to divide the area of the room by the length of the room.

So: 131 1/4 divided by 12 1/2 = width

width= 10 1/2

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
