Question

the diagonal of a quadrilateral is 28.4 cm long the perpendicular distance of diagonal from opposite vertex are of length 7.2 cm and 8 cm find the area of a quadrilateral​

Answer 1

Answer:

Answer is 215.84 cm^2

Step-by-step explanation:

Diagonal of the quadrilateral = 28.4 cm

length of height = 7.2cm and 8 cm

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

1/2×(7.2+8)×28.4

=215.84cm^2

Answer 2

Answer:

formula is 1/2d (h1+ h2)

so here diagonal is 28.4 m long

and other sides r of 7.2 and 8 cm

so here we will do

1/2 ( 7.2 + 8 ) 28.4 cm

215.84 cm square...

so the answer is - 215.84 cm square...
