Question

the area of square plot is 4900m square 2 find the length of rope which can go 4time around the boundary of this plot​

Answer 1

Answer:

1120 m

Step-by-step explanation:

given: area of a square plot=4900 m

side^2=4900

side=root 4900

side=70

so, perimeter= 4( side)

=4x70

=280 m

so length of rope which can go four times around the boundary

=4* perimeter

=4*280

=1120 metres

Answer 2

Answer:

The length of rope which can go 4 times around the boundary of this plot = 1120 m

Step-by-step explanation:

Given that:

The area of square plot is 4900 m²

Formula used:

Area of square = a² sq. unit

Perimeter of square = 4a unit

Here, Edge of square is denoted by a.

Finding the length of each side of square plot:

→ 4900 m² = a²

→ a² = (70 m)² [Power get cancelled]

→ a = 70 m

∴ Each side of square plot = 70 m

Finding the length of the boundary of square plot:

Perimeter of square = 4 × 70 m

Perimeter of square = 280 m

∴ Length of the boundary of square plot = 280 m

To find:

The length of rope which can go 4 times around the boundary of this plot.

Finding the length of rope which can go 4 times around the boundary of this plot:

= 4 × Length of boundary of square plot

= 4 × 280 m

= 1120 m
