Answer 2

Answer:

length of plot initially is 20m.

length increase = 10/100× 20

= 2m

now the length become 20m + 2m = 22m

breadth of plot initially was 15m

breadth increase = 15/100×15

= 2.25m

now the breadth will 17.25m.

area of plot initially = 20×15

= 300m2

now area of plot will 22× 17.25

=379.5 m2

% increase in area = 79.5/300×100

=26.5%
