Answer 1

Answer:

A=70cm

B=80cm

C=90cm

Semi-perimeter =

2

(70+80+90)

=

2

240

=120cm

Area of triangle =

s(s−a)(s−b)(s−c)

=

120(120−70)(120−80)(120−90)

=

120×50×40×30

=

4×3×10×5×10×3×10×4×10

=4×3×100

5

=1200×2.23

=1200×

100

223

=2676cm

2

∴ Area of triangle =2676cm

2The sides of a triangle are 70 cm, 80 cm and 90 cm. Find it area.

Answer 2

Answer:

The raw vegetables and fruits are kept in the refrigerators whereas the pickles and jams are kept outside because the pickles and jams contain some preservatives such as sugar, salt, and other ingredients in them. ... This eliminates much of the foodborne pathogens that would otherwise spoil the jam.
