Brooks wants to fence his square field of side 70 m. If he would need to fence the field twice, then find the cost of fencing at $0.50 per m.
Answers
Solution!!
The side of the square field is given in the question. The field has to be fenced twice. The cost of fencing the field peri metre is given in the question. We have to find the total cost of fencing the field twice.
Side = 70 m
As we all know that fencing is done on the perimeter of the field, so we will find the perimeter of the square field.
Perimeter = 4 × Side
Perimeter = 4 × 70 m
Perimeter = 280 m
Now, the 280 m is the distance that has to be fenced. We have to fence twice so we will multiply the perimeter by 2. Hence, we will know the total length of fencing which needs to be done.
Total length of fencing = 280 m × 2 = 560 m
Now, we know that,
Cost of fencing 1 metre = $0.50
Cost of fencing 560 metre = $0.50 × 560
Total cost of fencing = $280
Answer:
280
Step-by-step explanation:
70 x 0.50 = 35 dollars for 70 meters
35 x 4 = 140 dollars
140 x 2 = 280
