Can you find the y variable?

ELEN [110]

Answer:

$\large\boxed{y=27}$

Step-by-step explanation:

Look at the picture.

ΔADC and ΔCDB are similar (AA). Therefore the sides are in proportion:

$\dfrac{AD}{DC}=\dfrac{DC}{DB}$

We have:

$AD=12,\ DC=18,\ DB=y$

Substitute:

$\dfrac{12}{18}=\dfrac{18}{y}$ cross multiply

$12y=(18)(18)$

$12y=324$ divide both sides by 12

$y=27$

Find the area of the rhombus. 4.32 m2 2.16 m2 1.08 m2 1.05 m2

S_A_V [24]

Answer:

Step-by-step explanation:

Alright, lets get started.

The part of the diagonals are given as 0.9 m and 1.2 m.

The diagonals of rhombus intersect each other.

Hence the length of diagonals will be : $0.9*2=1.8$ and $1.2*2=2.4$

The formula of area of rhombus is : $\frac{pq}{2}$ where p and q are the length of diagonals.

So plugging the values of diagonals in formula, the area will be :

Area = $\frac{1.8*2.4}{2}$

Area = $\frac{4.32}{2}$

Area = $2.16 \ m^2$ ................. Answer

Hope it will help :)
