Question

Perimeter of the rhombus is 100m and it's diagonal is 40 m. Find the area of rhombus

Answer 1

Answer:

600metre square.

Step-by-step explanation:

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 2

If perimeter is 100m then its sides are:-

P===4S

100==4S

SO, S=100/4=25m

If it's one diagonal is 40 then it's another diagonal is ==30m

Then the area of the rhombus is

R=diagonal A x diagonal B / 2

= 40x30/2

= 600m²
