Answer 2

Answer:

Area = 16.1 unit²

Perimeter = 339/20 unit

Step-by-step explanation:

Given parameters :

Length of rectangle = $\sf{5 {\dfrac{3}{5}}}$ unit

Breadth of rectangle = $\sf{2 {\dfrac{7}{8}} }$ unit

We can write them in improper fraction as :

Length = $\sf{ {\dfrac{5 × 5 + 3}{5}}}$

= $\sf{ {\dfrac{28}{5}}}$ unit

Breadth = $\sf{ {\dfrac{8 × 2 + 7}{8}}}$

= $\sf{ {\dfrac{23}{8}}}$ unit

Now,

Perimeter of rectangle = 2(length + breath)

= 2( $\sf{ {\frac{28}{5}} + {\frac{23}{8}}}$ )

= 2( $\sf{ {\frac{(28)(8) + (23)(5)}{40}}}$ )

= 2( $\sf{ {\frac{339}{40}}}$ )

= $\sf{ {\dfrac{339}{20}}}$ unit

Area of rectangle = Length × Breadth

= $\sf{ {\dfrac{28}{5}} × {\dfrac{23}{8}} }$

= 16.1 unit²
