Question

diagonals are 12 and 16 find the perimeter ​

Answer 1

Answer:

40

Step-by-step explanation:

Diagonal of rhombus = 12cm and 16cm

half of diagonal = 6cm and 8cm

by using Pythagoras theorem

at the point o where diangonals are meet at that point there are angle formed 90°

so,

a (side) of rhombus = √p² + b²

a = √6² + 8² = √36+64 =√ 100 = 10cm

now , as we know that Perimeter of rhombus

= 4a = 4×10 = 40cm
