Question

a rectangular field has side lengths that measure 9/10 mile and 1/2 mile what is the area of the field

Answer 1

0.45

Step-by-step explanation:.b

Answer 2

`(9)/(20)miles^2=0.45miles^2`

Explanation:

To find the area of a rectangle:

`a=l*w`

where
`l` is the length and
`w` is the width.

In this case:

length:
`l=(9)/(10)miles`

width:
`w=(1)/(2) miles`

thus, we multiply this quantities to find the area:

`a=((9)/(10) miles)((1)/(2)miles )\\\\a=(9*1)/(10*2)miles^2\\ \\a=(9)/(20)miles^2`

the area of this rectangle is 9/20 miles squared, or what is the same 0.45 miles squared
