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:
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
