Let L = Length, and W = Width. We are given the fact that L = 2W, and also know that the area = L x W = 50 square feet. So, by substitution: 2W x W = 50 sq ft, or 2W^2 = 50 sq ft, so W = sq rt (50/2) = 5 ft. Now, L = 2W = 2(5) = 10 ft. The perimeter of the fence is given by: 2L + 2W = 2(10 ft) + 2(5 ft) =20 ft + 10 ft = 30 ft. So, Ben needs 30 ft of fencing.
Answer:
x+5
Step-by-step explanation:
Side is equal to sqrt area
= sqrt x^2 +10x + 25
= x+5
So one side of the square is x+5 metres
Answer:
10
Step-by-step explanation:
8+5+15+12+10= 50 / 5 = 10
If you graph the points it comes out as a square, so the correct answers would be square, rectangle, parallelogram, and rhombus (a square can be these three but these shapes cannot be squares)
Answer: long range
Explanation: it mainly effects long range areas but can also affect short range if it need to
