Hi I think this is how it should be done, not completely sure please check other scources as well For this question to be answered at least a basic shape is required, is it a rectangle, is it a circle. The optimisation of the perimeter of a rectangle or square could be found ...

if you double the length, you double the area to have an area of 55 and a perimeter of 32, the original garden was 5 X 11 so the increase in perimeter is 22 __ the percentage is __ (22/32) * 100

Algebra 1
make a sketch and label the width x, then the length must be 2x the perimeter would be 2(x+2x) = 6x and the area would be x(2x) = 2x^2 <<The number of feet in the perimeter of the garden is equal to the number of square feet in its area>> 6x = 2x^2 2x^2 - 6x=0 2x(x...

Bernie put in a garden in her back yard. The garden has a perimeter of 272 feet. She wants to know the total surface area of the garden and all she knows is the perimeter and that the width is 20% or (1/5) of the length. (Remember 20% and the fraction 1/5 is the same decimal ...

Pre-Calculus
A window has the shape of a square surmounted by an isosceles triangle. The sides of the square are length x. The The perimeter of the window is 90 inches. Thus, the perimeter of the triangle is x+2y. So, 90 inches = 3x+2y. (a) Write an equation for the area of the window in ...

Need to tell the appropriate measure for finding the amount of fencing to enclose a rectangular garden. Have to choose between perimeter and area. Would it be perimeter?

geometry
Considering all rectangles with a given perimeter, which one encloses the largest area? The traditional calculus approach would be as follows. Letting P equal the given perimeter and "x" the short side of the rectangle, we can write for the area A = x(P - 2x)/2 = Px/2 - x^2. ...

Not quite! The lateral area of a pyramid, A =(1/2)(base-perimeter)* slant height So given A=300, base perimeter =100 we have slant height = A*2/base-perimeter=6 units
