For the first field, he will need 40 m for the fence, this will cost £640 and he can have 10 sheep. For the second field, he will need 60 m for the fence, this will cost £960 and he can have 12 sheep.
This problem requires you to calculate the perimeter and area of each field and based on this information you can find the total of the fence the farmer requires, the cost, and the number of sheep.
You can calculate the perimeter by adding all the sides.
To calculate the area, multiply the height by the width.
The fencing needed is equal to the perimeter.
Multiply the number of meters needed by the price per meter ( £16 per meter).
To calculate this divide the area into the space required by each sheep (10m2).
