Question

Find the measure of the side of a rhombus if it's diagonal measure 35cm and 28cm

Answer 1

Let the side be x,

As we know that diagonals of rhombus bisects each other by 90°,

By Pythagoras theorem,

(35/2)² +(28/2)² =side²

1225/4 +14² =side²

(1224 +196)/4 =side²

1420/4 =side²

√{1420/4} =side


√355 =side

18.84 =side


I hope this will help you

Answer 2

Let the side be x cm.
As we know that diagonals of rhombus bisects each other by 90° as said first. By Pythagoras theorem,
(35/2)² +(28/2)² =side²
1225/4 +14² =side²
(1224 +196)/4 =side²
1420/4 =side²
√{1420/4} =side
√355 =side
18.84 =side
