Basically, this is saying that 80% of (x) = 2 so you have know what the whole would be. It would be 2.5 because 80% of 2.5 is 2. So because you are subtracting 7 from v to get 2.5, you have to add 2.5 to 7 to get v. V=9.5
Answer:
40cm
Step-by-step explanation:
A=s*s
A=10*10
A=100 cm^2
P=4*s
P=4*10
P=40 cm
"s" represents side
We know that
area of the tent=length*breath
length=240 cm---convert to m---> 240/100----> 2.40 m
breath=170 cm----convert to m---> 170/100----> 1.70 m
find the area
area=2.40*1.70-----> area=4.08 m²
therefore
the answer is
<span>the friend's statement is incorrect the area is 4.08 m</span>²
