The area of a rectangle is 21 in2. The length of the rectangle is 6 in.
IrinaVladis [17]
Given:
Area = 21 in²
length = 6 in.
width = ?

The area of a rectangle is computed by multiplying its length by its width.

A = l * w
21 in² = 6 in * w

To find width, divide the area by its length.

21in²/6in = w
3.5 in. = w.

The width is 3.5 inches.

to check:

Area = Length * Width
21 in² = 6 in x 3.5 in
21 in² = 21 in²

The equation A = x(x-4) describes the area, A, of a rectangular flower garden, where x is the width in feet.
BabaBlast [244]

Answer:

The flower garden width would be 6 ft

Step-by-step explanation:

A = 12 ft^2 = x(x + 4) becomes:

x^2 + 4x - 12 = 0, or (by completing the square) x^2 + 4x + 4 - 4 - 12 = 0

Thus, we have (x + 2)^2 - 16 = 0, or (x + 2)^2 = 16

Taking the square root of both sides yields x + 2 = ±4.

In this context only a positive x value makes sense:  x = 2 + 4  =>  x = 6.

The flower garden width would be 6 ft.  The other dimension would be 6 - 4, or 2, ft.

PLEASE HELP!!
Radda [10]

Answer:

C.) 2\sqrt{34}

Step-by-step explanation:

<em>You must use the pythagorean theorem</em>

the distance on the x axis (or a) is 6

the distance on the y axis (or b) is 10

6^{2}  + 10^{2} = 136

\sqrt{136} = 2\sqrt{34}
