Answer 2

Answer:

$2.3$

Step-by-step explanation:

Given data:

• Length of the rectangle $=\frac{3}{4}$

• Breadth of the rectangle $=\frac{2}{5}$

We know that,

• Perimeter of a rectangle $=2(length+breadth)$

On substituting the values, we get

• Perimeter of the rectangle

$=2(\frac{3}{4}+\frac{2}{5} )$

• To add the given fractions, we need to find the LCM of denominators

• LCM of $4,5=20$

$=2(\frac{15+8}{20} )$

$=2(\frac{23}{20} )$

$=2.3$

Hence, the Perimeter of the rectangle $=2.3$.
