Question

perimeter of a rhombus is 100 M and its diagonal is 40 m find the area of the Rhombus

Answer 1

perimeter=100 m
we know that the sides of the diagonal are equal
therefore
each side
=100/4
=25 m

the other diagonal
=√25²-20²*2
=√625-400*2
=√225*2
=15*2

therefore area =1/2*30*40
=15*40
=600 m²(answer)

Answer 2

perimeter=100 m

we know that the sides of the diagonal are equal

therefore

each side

=100/4

=25 m

the other diagonal

=√25²-20²*2

=√625-400*2

=√225*2

=15*2

therefore area =1/2*30*40

=15*40

=600 m²(answer)
