Question

Sam is planting a garden that measures

6.5
feet in width and
9.8
feet in length.

Which is the BEST estimation for the area of Sam's garden using a rational approximations

Answer 1

63.7 feet

Explanation:

We can re-write the width and the length both as rational numbers:

- Width:
`w=6.5=(65)/(10)`

- Length:
`L=9.8=(98)/(10)`

So now we can find the area of the garden by multiplying width and length:

`A=wL=(65)/(10)\cdot (98)/(10)=(65\cdot 98)/(10\cdot 10)=(6370)/(100)=63.7`
