Question

Can someone help me with this question please?

Answer 1

We are given a parallelogram with sides:

3 1/8 and 2 3/16.

Let us convert each into improper fraction.

3 1/8 = 25/8

2 3/16 = 35/16

Now perimeter of parallelogram is given by:

$P = 2(sum of non parallel sides)$

$P= 2(\frac{25}{8} + \frac{35}{16})$

Now we have to find lcd of 8 and 16.

lcd of 8 and 16 is 16.

$P= 2(\frac{25*2}{8*2} + \frac{35}{16} )$

$P=2( \frac{50}{16} + \frac{35}{16} )$

$P= 2(\frac{50+35}{16} )$

Perimeter = 85/8 km

Answer : Perimeter of parallelogram is given by 85/8 km.
