the length of a rectangle is equal to triple the width . if the perimeter is 8 centimeters .what is the length and the width of
madam [21]

Answer:

Length = 3 cm

Width = 1 cm

Step-by-step explanation:

Let the length of rectangle be l and width of rectangle be w.

According to problem,

l = 3w  {Length of rectangle is equal to triple the width}

And Perimeter,P = 8 cm

Since, P = 2 ( l + w )

or 8 = 2( l + w)

Plug l =3w in the above perimeter equation.

We get:

8 = 2( 3w + w)

8 = 2(4w)

8 = 8w

or    w = 1 cm

Then length ,l = 3w =3 * 1 = 3 cm

Hence length of rectangle is 3cm and width of rectangle is 1cm.

Answer/Step-by-step explanation:

Quotient is simply the ratio of the first numerator to the second numerator:

Let's \frac{x_1}{y}\;and\;\frac{x_2}{y} are two fractions in same terms.

Thus, \frac{x_1}{y}\div\frac{x_2}{y} {Divided by a fraction is equal to multiplied by its reciprocal}

=\frac{x_1}{y}\times\frac{y}{x_2}

Quotient is simply the quotient of their numerators.

Example could be:

\frac{2}{7}\div\frac{3}{7}

\frac{2}{7}\times\frac{7}3}

\frac{2}{3}

2 is first numerator and 3 is the second numerator.
