Lori is drawing a picture of her dining room. the scale in her drawing is 3in : 6ft. the length of the living room is 8 inches and the width is 15 inches. what are the length and width of the actual room? find the area of the actual room.

480 ft

Step-by-step explanation:

1 ft = 12 in, so 3in : 6ft would be 3in : 72in, which can be simplified to 1in : 24in. then you use the scale to find the lengths. 8in: (24·8)in. 24 · 8 = 192. to convert to feet, do 192/12=16ft. for the width, do the same thing. 15in: (24·15)in. 24·15=360. 360/12=30ft. For area, multiply the length and width. 16·30=480ft.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

the answer is b
