Hi there !!
The answer is option (a)
We know that , the formula for the area of a general quadrilateral is:
where,
d is the diagonal and h1 and h2 are the height,
Diagonal = 4cm
h1 = 1cm
h2 = 2cm
Substituting the value,
we have,
= 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..!!
