Question

Each side of a rhombus is 13 CM and one diagonal is 10 CM. Find
1) the length of its other diagonal
2) the area of the rhombus

Answer 1

Answer:

1)24 cm 2)120 cm2

Step-by-step explanation:

1)one diagonal is 10 cm a rhombus opposits sides are parallel and equal half of a diagonal is 5 cm then according to pythagorus theorem a2+b2=c2 then a2+5^2=13^2 then a2+25=169 then a=√169-25 a=√144 a=12 cm 12 is half of its diagonal diagonal =2a =2*12=24 cm. 2)area of rhombus =(diagonal 1*diagonal 2)/2 then (10*24)/2 = 120cm2
