Question

in a rhombus , if diagonals are 30cm and 40 cm , find its perimeter​

Answer 1

Answer:

The diagonals being 30 cm and 40 cm, the half lengths are 15 cm and 20 cm. ... By Pythagoras' Theorem, each side of the rhombus measures sqrt(15^2 + 20^2) = 25 cm. Therefore, the perimeter of the rhombus is 4 x 25 cm = 100 cm or 1 metre.

Answer 2

Answer:

100 cm

Step-by-step explanation:

Diagonals are 30 cm and 40 cm.

As we know that diagonals of rhombus cut each other in equal parts also they bisects at 90°.

So, by pythagoras theorem

= root 15² + 20² cm

= root 625.

= 25 cm

Sides of rhombus measure 25 cm

perimeter

= 4a

= 4×25.

= 100 cm
