Question

The area of a rhombus is 2076 square. Cm and its sides are equal to 65 cm. Find the length.

Answer 1

Answer:

Step-by-step explanation:

area=1/2xy(x and y are lengths of diagonals)=2016

xy=4032cm^2 - (1)

square root((x/2)^2+(y/2)^2 =65

x^2+y^2=16900cm^2 -(2)

(x+y)^2=x^2+y^2+2xy

from 1 and 2

x+y=158 - (3)

and (x-y)^2=x^2+y^2 -2xy

(x-y)=94cm - (4)

from 3 and 4

x=126

y=32
