So, first, what are the two sides?
let's call then x and y
we know that 2(x+y)=12.5 (that's the distance around)
so that means that x+y=6.25 (I just divided both by 2)
now, x=4y (from "4 times as long as it is wide")
so we can substitute:
x+4x=6.25
5x=6.25
x=1.25
so one side, is 1.25 and the other will be 1.25*4=5
and for the area we multiply the two:
1.25*5=6.25 square kilometers, and this is the answer!
The answer is 26. You do 10/1 multiplied by the reciprocal of 5/13 which is 13/5. If you multiply them you get 130/5 which when simplified is 26.
Answer:
8
Step-by-step explanation:
5) w/8 =11+5 → w/8=16
w=16÷8=2
6)a/-2 -6=1
a/-2=7
a=7×-2=-14
7)k/2=22
k=44
The answer is the fraction is 66/100 or simplified, 2/3<span />
