Question

There are 640 acres in a square mile. How big( in acres) is a rectangular field that is 0.3 miles by 1.3 miles?

Answer 1

Area= L*W so Area= 1.3miles*.3miles=0.39miles^2 so then 

Area in acres = 0.39miles^2 * 640acres/1sq mile = 249.6 acres

hope this helps! Thank you!

Answer 2

Based on the calculations, this rectangular field is 249.6 acres.

Given the following data:

• A square mile = 640 acres

• Length of rectangular field = 0.3 miles

• Width of rectangular field = 0.3 miles

To determine how big( in acres) is this rectangular field:

First of all, we would calculate the area of this rectangular field.

Mathematically, the area of a rectangle is given by the formula;

$A=LW$

Where:

• A is the area of a rectangle.

• L is the length of a rectangle.

• W is the width of a rectangle.

Substituting the given parameters into the formula, we have;

$A=0.3 \times 1.3$

Area, A = 0.39 $m^2$

Now, we can calculate its size in acres:

Conversion:

1 $m^2$ = 640 acres

0.39 $m^2$  = X acres

Cross-multiplying, we have:

$X = 640 \times 0.39$

X = 249.6 acres
