Question 884873
Area = length * width
Factors of 154 are:
1, 2, 7, 11, 14, 22, 77, 154
The perimeter fence is 2L + 2W.  In this case 50cm.  So L + W would be half that, or 25.
Which factors of 154 sum to 25?
Only 11 and 14.
The length is 14 and the width is 11.
The perimeter is 14+14+11+11 or 50
The area is 14 * 11, or 154
