Question

the square park is of side 100m A path 5m wide is made all around the garden inside it find the area of the path

Answer 1

hello

area of square = 100²

= 10000cm²

side of inside park = 100 - 2 * 5 = 90

area of inside path = 90²
= 8100

area of path = 10000 - 8100

=1900cm²

Answer 2

In the above figure:-
ar (ADHE)=100×5
=500m*---------------------(1)
Similarly,
ar (FGCB)=100×5
=500m*------------------(2)
now, EF=100-(5+5)
=90m
ar (EFJI)=90×5
=450m*---------------------(3)
Similarly,
ar (HGKL)=90×5
=450m*-----------------(4)
On adding (1),(2), (3) and (4)
we have,
500+500+450+450
1000+900
1900m*
