Question

Determine the perimeter of the rectangle. L=3/4cm, W=7/8cm

Answer 1

Answer:

The perimeter of the rectangle with L= $\frac{3}{4}$ cm and W $= \frac{7}{8}$ cm is 3.25 cm or $\frac{13}{4}$ cm

Solution:

Given, the length of the rectangle is L = $\frac{3}{4}$ cm

And, the width of the rectangle is W = $= \frac{7}{8}$ cm     We have to find the perimeter of the given rectangle.

We know that, perimeter of a rectangle is given by

P = 2( L + W )

So, let us substitute the above given values in the formula of perimeter of a rectangle.

$P=2\left(\frac{3}{4}+\frac{7}{8}\right)$

Multiplying 2 on numerator and denominator, to get both denominators equal.

$\begin{array}{l}{\mathrm{P}=2\left(\frac{2 \times 3}{2 \times 4}+\frac{7}{8}\right)} \\\\ {=2\left(\frac{6}{8}+\frac{7}{8}\right)} \\\\ {=2\left(\frac{6+7}{8}\right)} \\\\ {=2 \times \frac{13}{8}=\frac{13}{4}=3.25}\end{array}$

Hence the perimeter of the rectangle with L= $\frac{3}{4}$ cm and W $= \frac{7}{8}$ cm is 3.25 cm or $\frac{13}{4}$ cm

Answer 2

Answer:

4 and 1/4

Step-by-step explanation:

3/4 =6/8 and 6/8 plus 6/8 plus 7/8 plus 7/8 = 26/8 = 4 and 1/4
