Question

The diagonal of a quadrilateral intersect each other at right angle. If the length of these diagonal be 14cm and 19cm. Find the Area of the quadrilateral

Answer 1

hey friend!!
here's your answer...
since the diagonals intersect each other at right angle and diagonals are not equal...so it's a rhombus..
Area of rhombus is=1/2×d1×d2
1/2×14×19= 7×19= 133 sq cm
hope it helped u...thank you!!
:)

Answer 2

The area of quadrilateral is 133 sq. cm.

Step-by-step explanation:

Since we have given that

The diagonal of a quadrilateral intersect each other at right angle.

So, the quadrilateral becomes "Rhombus".

Length of first diagonal = 14 cm

Length of another diagonal = 19 cm

So, the area of rhombus becomes

$\dfrac{1}{2}\times d_1\times d_2\\\\=\dfrac{1}{2}\times 14\times 19\\\\=7\times 19\\\\=133\ cm^2$

Hence, the area of quadrilateral is 133 sq. cm.
