Ascale drawing for a rectangular parking lot measures 6.8 cm by 12.3 cm. the scale is 5 cm : 25 cm. find the area of the parking lot.

The scale drawing: 83.64 centimeters. The scale: 125 centimeters.

Step-by-step explanation:

6.8 multiplied by 12.3 equals 83.64, and 25 multiplied by 5 equals 125. Hope this helped! :D

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
