Question

-The diagonals of a rhombus are 6 cm and 8 cm. Find the length of a side of
the rhombus and hence its perimeter.​

Answer 1

Answer:

The diagonals of a rhombus are 6 cm and 8 cm.  Then the length of a side of

the rhombus is 5 and  its perimeter is 20 .​

Step-by-step explanation:

the formula to calculate the side ,where P and Q are diagonals

a = \frac{\sqrt{P^{2\;}+q^2}}2

a= \frac{\sqrt{6^{2\;}+8^2}}2 = 5

for to calculate perimeter of a rhombus is where P and Q are diagonals

2\times\sqrt{P^{2\;}+Q^2}

2\times\sqrt{6^{2\;}+8^2} = 20
