Answer:
105 km
Step-by-step explanation:
Written as a proportion, the ratio of km to cm will be the same for both distances:
(x km)/(17.5 cm) = (15 km)/(2.5 cm)
x km = (15 km)(17.5/2.5) = 105 km
105 actual kilometers are represented by 17.5 cm on the map.
Let width be x
Length; 6+2x
p=2(l+w)
7878=2((6+2x)+x)
7878=2(6+3x)
7878=12+6x
7878-12=6x
7866=6x
7866/=x
1311=x
Therefore, the width is 1311 meters, length is (6+2(1311)=2628 meters
Hope I helped :)
I think you're wondering how to say this equation in words; you say 2 times the quantity x minus 7 plus 10.
Is it Add? Or is it wrong or just a misunderstanding
