Mathematics

8 0

a) Area of rhombus = ½ * (diagonal1)*(diagonal 2)

Let diagonal (D2 )= longer diagonal = 15 and diagonal (D1) = shorter diagonal

90 = ½ (D1)*15

90 = 7.5 D1

Now divide both side by 7.5

90/7.5 = d1

D1= 12 units.

b) Area of rhombus = ½ * (diagonal1)*(diagonal 2)

Let the ratio be x

Diagonal 1= 2x

Diagonal 2= 3x

147 = ½ * (2x)*(3x)

Multiply both side by 2

294 = (2x)*(3x)

294 = 6x^2

Divide both side by 6

294/6 = 6x^2/6

49 = x^2

x= 7 unit
