Question

Each side of a rhombus is 13 cm and one diagonal is 10 cm then find:(1) the lenght of irs other diagnol (2) the area of the rhombus

Answer 1

hey mate here is your answer -----
side of the rhombus=13 cm
one diagonal d1 =10 cm
second diagonal d2 = ?

1.by using Pythagoras theorem
ab2 = ao2+ ob2
13×13 = 5×5 + ob2
ob2 = 196-25
ob2= 144
ob = 12 cm

diagonal d2 = 2×12
= 24 cm
2. area of the rhombus= 1/2×d1×d2
= 1/2×10×24
= 120 cm2.
