Question

A diagonal of a rhombus having area 70 sq. cm is 10 cm. Find the length of the other diagonal.

Answer 1

Answer:

The length of the other diagonal is 14 cm.

Step-by-step explanation:

Let,

the length of others diagonal=x cm

Area of the rhombus=70 sq. cm

ATQ,

Area of a rhombus= 1/2(d1 ×d2) [d1- first diagonal

d2- second diagonal]

=>70=1/2(10×x)

=>70=1/2×10x

=>70=10x/2

=>10x×1=70×2

=>10x=140

=>x=140/10

=>x=14

so, the length of the other diagonal =x cm=14 cm.
