Answer 2

Answer:

proved

Step-by-step explanation:

Given that the perimeter of the square field garden is 40 m

we know the perimeter of the square is 4a where a is the length of one side

here 4a=40

so from here we get a=10 m

so the length of one side is 10 m

we have to prove area of the square is 100 square meters

we know the area of the square is = a×a

here a =10 m

so the area of the square is 10×10=100 square meters (proved )
