Answer 2

The length of rectangular plot is 40468600 cm.

Step-by-step explanation:

Given : The area of a rectangular plot is 80 acres its breadth is 80 cm.

To find : Its length ?

Solution :

The area of a rectangular plot is 80 acres.

Convert acre into square meter,

1 acre = 4046.86 m²

80 acres = 4046.86 × 80 m²

80 acres = 323748.8 m²

Breadth is 80 cm.

Convert into m,

1 cm = 0.01 m

80 cm = 0.8 m

The area of the rectangular plot is $A=l\times b$

$323748.8=l\times 0.8$

$l=\frac{323748.8}{0.8}$

$l=404686\ m$

or $l=40468600\ cm$

Therefore, the length of rectangular plot is 40468600 cm.
