Answer 1

Answer:

Perimeter=160 m

Area=1520 m sq.

Step-by-step explanation:

The perimeter is 164 m.

Therefore, round off is 160 m.

The area is 1519.71 m sq.

Therefore, round off is 1520 m sq.

Answer 2

Answer :

• Perimeter of land is 160.
• The area of grass needed to fill up the entire plot of land is 1500 m²

Solution :

Given :

• The dimensions of a rectangular plot of land are 28.3 by 53.7 m.

To Find :

• (i) The perimeter of the land. {nearest to 10 m} ,
• (ii) The area of grass needed to fill up the entire plot of land { nearest to 100 m²} .

✯ Solving for perimeter of the land :-

we know that,

$\red\bigstar\: \boxed{ \sf Perimeter \: of \: rectangle = 2(length + breadth) }$

Putting the values here,

$\leadsto \text{\bf Perimeter of land} = 2(28.3+53.7) \\\\ \implies \text{\sf Perimeter of land} = 2(82)\\\\ \implies \text{\bf Perimeter of land} = \underline{\boxed{\pink{ 164m }}}$

It is given that we have to find perimeter nearest to 10m. So, Perimeter of land will be 160 m.

Hence,

Perimeter of land is 160.{nearest to 10m}.

✯ Solving for area of grass needed

$\red\bigstar\: \boxed{ \sf Area \: of \: rectangle = length \times breadth}$

Putting the values :-

$\leadsto \text{\bf Area of land } = 28.3 \times 53.7 \\ \\ \leadsto \sf \text{\bf Area of land } =\underline{\boxed{\pink{ 1,519.71 m^2 }}}$

It is given that we have to find Area nearest to 100 m². So, Area of land will be 1500 m².

Hence,

The area of grass needed to fill up the entire plot of land is 1500 m²{nearest to 100m²}.
