# Length of height of rhombus is 4 cm. and length of side is 5 cm. What is the area of field in the shape of rhombus.

Answer :

Given, Length of height of rhombus is 4 cm. and length of side is 5 cm.

Hence, DB= 4cm and then BO = 2cm

By Pythagoras theorem,

BO^{2} + AO^{2} = AB^{2}

2^{2} + AO^{2} = 5^{2}

AO^{2} = 25 – 4

AO =

AO = 4.6cm

Hence, AC = 2.AO

AC = 2×4.6

AC = 9.2 cm

Area of rhombus = ×4×9.2

= 18.4 sq. cm
