Question

The perimeter of a rhombus is 260 cm and one of its diagonal is 66cm .Find the area of rhombus and its other diagonal

Answer 1

Answer:

Find the perimeter of a rhombus

17,160

Answer 2

Rhombus each side is equal

So ,

One side =260÷4=>65cm

One diagonal is 66cm

So,

Half of diagonal=66÷2=>33cm

Using Pythagoras theorem we can find its another diagonal

Let another half diagonal be 'x'

65²=x²+33²

65²-33²=x²

56cm=x

Another diagonal=2×56=>112cm

Area of rhombus=1/2×product of diagonal

=1/2×112×66

=3696cm²
