Ответ:
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
Ответ:
Area = 21 inches²
Length = 6 inches
Width = x inches
We can use this formula to solve for the width:
Area = Length × Width
21 inches² = 6 inches · x inches
21 inches² = 6x inches²
21 = 6x
Now, divide both sides by 6.
21/6 = 6x/6
21/6 = x
The width is 3.5 inches.
