​

Answer 1

Answer:

Given:

⇒ABCD is a rhombus

⇒For ΔBCD

Perimeter

=8+30+30

=108 cm

⇒2S=108 cm, S=54 cm

⇒Area of ΔBCD

A=√s(s-a)(s-b)(s-c)

=√54(54-48)(54-30)(54-30)

=√54×6×24×24

= ___

√72×6

=432m*2

⇒Area of field

=2× Area of ΔBCD

=4×432m*2=864m*2

⇒Area of grass field each cow be getting

=864/14

=48m*2
