Hi there !!
The answer is option (a)
We know that , the formula for the area of a general quadrilateral is:

 \frac{1}{2} d(h1 + h2)
where,
d is the diagonal and h1 and h2 are the height,
Diagonal = 4cm
h1 = 1cm
h2 = 2cm

Substituting the value,
we have,

 \frac{1}{2}  \times 4(2 + 1)

= 6cm²


So,
the area of the given quadrilateral is 6cm²

hiii!!!

here's ur answer...

area of quadrilateral = 1/2 × d ( h1 × h2 )

given diagonal of the quadrilateral is 4cm.

both h1 and h2 are the height of two triangles in the quadrilateral.

h1 = 1cm

h2 = 2cm

area of the quadrilateral = 1/2 × 4 ( 1 + 2 )

= 2 × 3

= 6cm²

hence, correct option is (a) 6cm²

we can find it's area with one more method.

but it's little longer

as there are two triangles. let one triangle be A and another be B.

height of the triangle A = 1cm

base of the triangle A = 4cm

area of triangle A = 1/2 × b × h

= 1/2 × 4 × 1

= 2 × 1

= 2cm²

height of triangle B = 2cm

base of triangle B = 4cm

area of triangle B = 1/2 × b × h

= 1/2 × 4 × 2

= 2 × 2

= 4cm²

so, total area = 2 + 4 = 6cm²

u can solve this in two methods, but first one is shorter.

hope this helps..!!
