A farmer plows a corn field in the shape of a rectangle that has an area of 15840 square yards if the length of the field is 132
igomit [66]

Answer:

<u>Width= 120</u>

<u />

Step-by-step explanation:

We know that <u>L*W= A</u>

So lets put in the variables we know into the equation.

<u>L= 132 yards</u>

<u>A= 15840</u>

132 * W= 15840

All we need to do is <u>divide 15840 by 132</u>

<u>15840/132= 120</u>

<u>W=120</u>
