Question

the perimeter of a square field in 8km find its area in hectares ?​

Answer 1

Answer:

Step-by-step explanation:

LET THE SIDE OF THE SQUARE FIELD BE "a"

PERIMETER OF A SQUARE ,P = 4*a.

GIVEN 4*a = 8 KM

a = 8/4

a = 2 KM.

AREA OF THE SQUARE , A = a².

                                               = 2*2

                                               = 4 KM².

NOTE :

1 KM² = 100 HECTARES.

4 KM ² = 400 HECTARES.

THEREFORE THE AREA OF THE SQUARE FIELD IS 400  HECTARES.

HOPE THIS HELPS.
