Question

The dimensions of a rectangular plot of land are 21.5 m and 12.8 m. Find the

area of the plot. If the entire plot is to be fenced, what is the length of wire

required per round?​

Answer 1

Answer:

Area,Perimeter

Step-by-step explanation:

Area=21.5×12.8=27.52

Perimeter=68.6

Thus length of wire=68.6/m

Answer 2

Given that :-

⇒ The dimensions of a rectangular plot = $21.5 m; 12.8 m$

_________________________________

To find :-

⇒ ∴ Area of the plot.

⇒ ∴ Length of wire required for fencing the whole plot.

_________________________________

Solution :-

⇒ Area of rectangle = (L × B)

⇒ We know that fencing is done in the boundary $(Boundary = Perimeter)$.

Formula for area of rectangle = $2$ × (L + B)

_________________________________

Required :-

Area of the rectangular plot

⇒ L × B

⇒ $21.5 m$ × $12.8 m$

⇒ $275.2$$m$

Length of for fencing the rectangular plot

⇒ $2$ × (L + B)

⇒ $2$ × $(21.5 + 12.8)$

⇒ $55.8m$
