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
Answer:
The perimeter of the rectangle with L= [tex]\frac{3}{4}[/tex] cm and W [tex]= \frac{7}{8}[/tex] cm is 3.25 cm or [tex]\frac{13}{4}[/tex] cm
Solution:
Given, the length of the rectangle is L = [tex]\frac{3}{4}[/tex] cm
And, the width of the rectangle is W = [tex]= \frac{7}{8}[/tex] 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.
[tex]P=2\left(\frac{3}{4}+\frac{7}{8}\right)[/tex]
Multiplying 2 on numerator and denominator, to get both denominators equal.
[tex]\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}[/tex]
Hence the perimeter of the rectangle with L= [tex]\frac{3}{4}[/tex] cm and W [tex]= \frac{7}{8}[/tex] cm is 3.25 cm or [tex]\frac{13}{4}[/tex] cm
