Question 754577
let length of one diagonal of kite is x meter 
and length of another diagonal of kite is 2.5x
area of kite should be 2 square meter
area =1/2 multiplied by both diagonal
1/2 d1 multiplied by d2=2
1.2 multiplied by x multiplied by 2.5x =2
2.5x^2 =4
x^2 =4/2.5=1.6
x= 1.25 
one diagonal should be 1.25 m approx
other diagonal should be  1.25 x 2.5= 3.125 m approx
answer
