Question

a prayer hall is constructed in the middle of the plot of land 50m long and 30m broad around the Prayer hall is a space of uniform width 4.25 m find the area of this space​

Answer 1

Ar of hall= 50×30

=1500m^2

l of plot= 50+2(4.25)=58.5

b of plot= 30+2(4.25)=38.5

Ar of plot = 58.5×38.5

=2252.25

Ar of space= ar of plot- ar of hall

=2252.25-1500

=752.25m^2
