Question

solve this fast.................. Perimeter​

Answer 1

Answer:

we know that the diagonals of the rhombus are perpendicular bisectors of each otherWe can say that 8cm+8cm+8cm=16cm and 15cm+15cm=30.

Answer 2

Answer:

Area = 68 cm²

Step-by-step explanation:

1. Diagonals are 16 cm & 30 cm respectively....
2. Diagonals divide a rhombus into 4 equal right angled triangle..
3. So, for a Triangle, base and height will be half of the diagonals...

Therefore,

Base = 16 ÷ 2 = 8 cm

Height = 30 ÷ 2 = 15 cm

As, Base² + Height² = Hypotenuse² in a Right Angled Triangle.*

(8 cm)² + (15 cm)² = Hypotenuse²

⇒ Hypotenuse² = 64 cm² + 225 cm²

⇒ Hypotenuse² = 289 cm²

⇒ Hypotenuse = √289 cm²

⇒ Hypotenuse = 17 cm

Perimeter of a Rhombus = 4 × Hypotenuse

= 4 × 17 cm

= 68 cm

Here you GO!!!!

Hope you understood the method I've used...
