To calculate the length of the rectangle we let the length be x in, let width be
(2x-5) inches
The area will be given by:
A=length×width
A=x(2x-5)
but
A=700 in²
thus
700=x(2x-5)
700=2x²-5x
this can be written in quadratic form as:
2x²-5x-700=0
solving the quadratic we get:
x=20 or x=-35/2
since the length cannot be negative then:
x=20 in
thus the width will be:
2*20-5
=40-5=35 inches
Polygon Area = (see attached graphic)
Answer:
you can split the garden in: 1/2 circles x 4 (because you have 4 half-circles) + a square.
the square's area is 4 x 4 = 16; the circles is pi x R x R (pi = aprox 3.14, R of the cirlce is 4m / 2 = 2m, because the square's side is 4m and is the same size with circle diagonale: Diag of circle = 2 X Radius => Radius = Diag / 2)
than answer will be: 16 + 3.14 x 2 x 2 x 2 (the last 2 is, because you have 4 halves of circles, than you will have 2 full circles) = 45.12, than answer is H, because 41 is the nearest number to 45.12
there are 1000 milligrams in a gram, so
10 grams times 1,000 = 10,000 milligrams
