Answer:
a.) Total distance Julie cover = 128 feet
b.) Total area , the playground cover = 256 ft²
Step-by-step explanation:
P. S : The exact question is -
As given,
Length of 1 side = 16 feet
As , we have
4 sides of same length
⇒ Total length of playground = 16 + 16 + 16 + 16 = 16(4) = 64 feet
a.)
As given Julie does 2 lap of the playground
⇒ Total distance Julie cover = 64 + 64 = 128 feet
b.)
As the playground has equal side, so it must be of square shape
And, we know
Area of square = (Length of one side)²
= ( 16 )² = 256 ft²
∴ we get
Total area , the playground cover = 256 ft²
The decimal representation of any number is a linear combination of powers of 10. In other words, given a number like 123.456, we can expand it as
for any
, so the above is the same as
Similarly, we can write
Now it's a question of reducing the fraction as much as possible. We have so
