Question

The area of a square plot is 8100m² . find the length of the wire which can go five times along the boundary of the park.​

Answer 1

Answer:

1800m

Step-by-step explanation:

area area of the square given= 8100m^2

area of the square= side ^2

so,

(side)^2 = 8100m^2

Side = √8100 m

Side = 90m

we have to find the length of the wire which can go 5 times along the boundary of the square Park so we need to calculate the perimeter of the square ..

perimeter = side×4

perimeter = 90×4 m

perimeter = 360 m

360 metre is the length of wire which can go one time along the boundary of the park so for finding the length of the wire which can go 5 times we have to multiply this by 5.

total length of wire = 360×5=1800m
