Answer 1

Answer:

Neha:258 m^2

Nidhi:258 m^2

Step-by-step explanation:

Neha:

Total area= 2× area of trapezium

area of trapezium

=1/2h(s1+s2)

=1/2×6(15+28)

=3×43

=129 m^2

(i.e)= 2×129

=258 m^2

Nidhi:

Total area=area of∆+ area of rectangle

area of∆

=1/2 ×bh

=1/2×12×13

=6×13

=78 m^2

area of rectangle

=12×15

=180 m^2

total area

=78+180

=258 m^2
