question 3 today

one diagonal of a rhombus is 80 m if side of the Rhombus is 20 m find the height of the Rhombus

Answer 1

To find the length of a rhombus, use the formula of length = area ÷ base. If you know the diagonals of a rhombus but not its area, use the formula area = (d1 x d2) ÷ 2, then apply the area to the first formula.

I am giving you example in the attachment

Answer 2

The diagonals in a rhombus are perpendicular , and bisect each other

Given length of side is 10 cm and one diagonal as 12 cm we can find the length of other diagonal

From the  above figure let DB be the 12 cm diagonal,now OB and OD are 6 cm

Now consider triangle AOB ,this is a right andled triangle and we know AB=10cm and OB=6cm ,using Pythagoras theorem we can find out lenth of OA as 8cm ,so length of diagonal AC is 2*8=16cm

Area of rhombus is product of diagonal divided  by 2, 16*12/2=96 sq.cm

this is just an example so do according to your question
