Question

find the length of two diagonals ofva rhombus are 16cm and 30cm find the area and the length of the side of the rhombuss

​

Answer 1

Answer:

formula is 1/2×d1 ×d2

so 1/2×16×30

240cm^2

GIVEN :-

2 Diagonals of Rhombus = 16,30Cm.

TO FIND :-

Find the area and the length of the side of the Rhombus?

SOLUTION :-

Let ABCD is a rhombus

AB,BC,CD,AD are the sides of the rhombus and

AC and BD are the diagonals of the rhombus

Where

AC = 30

BD = 16

and o is the point where daigonals are bisect each other

As we know the property of rhombus that daigonals are bisect each other then

AO = CO = 15

BO = OD = 8

Since diagonals are perpendicular to each other then we can apply Pythagoras theoram on it

By applying Pythagoras theoram on ∆AOD

AD² = A0²+OD²

AD² = 15²+8²

AD² = 289

AD = 17Cm.

Since all the sides of the rhoumbus are congruent

Hence of the side of the rhoumbus is 17cm
