Yes it is. However if it has a variable you usually call it a function
Perimeter is equal to 2l+2w, or 2 times the length plus 2 times the width.
So to solve for this you'd take 2(6.5) + 2(4.23).
2(6.5)= 13
2(4.23)= 8.46
13+8.46= 21.46 meters.
Based on this, the answer is C.
3 minutes
10*8*12=960 cubic inches
960/320inches per minute =3
Number of Chickens 35
Number of Egg Production per Chicken 3
35 x 3 = 105
Richard can collect a total of 105 eggs per day.
