Question

the length of one of the diagonal of a rhombus is greater than other by 5cm.if it's area is 36 cm^2.find the length of the diagonal​

Answer 1

Answer:

area of rhombus =½×diagonal 1×diagonal 2

Step-by-step explanation:

let one diagonal is x

other is x+5

so area is =½× x×(x+5)

=36

so x^2+5x=72

now solve it

Answer 2

Step-by-step explanation:

let length of one diagonal = x

length of other diagonal be x+5

given area= 36 cm^2

area of rhombus = d1 × d2 /2

36 = x × x+5 /2

72 = x^2 + 5x

x^2 + 5x -72= 0

factorise it and find the value of x

the answer which is possitive will be your final answer
