Question

.
Find the length of the diagonal of a quadrilateral whose area is 195 sq. m and the lengths of the
perpendiculars to this diagonal from vertices are 9 m and 10.5 m respectively.​

Answer 1

Hence the lenght of the diagonal will be 20.

Answer 2

Answer:

20 will be the correct answer....

Step-by-step explanation:

formula to calculate area of quadrilateral is 1/2×d(H1+H2)

The area of quadrilateral is 195cm²

The length of perpendicular heights are 9m and 10.5m

The area of quadrilateral is given by

1/2×d×(h1+h2)

)

where d is length of diagonal

h1=9;h2 =10.5

so the correct answer is 20
