Dan says that all quadrilaterals are parallelograms. Tom says that it is not true. Explain who is correct??

Tom is correct

Step-by-step explanation:

Quadrilaterals are polygons that have four sides.

Square, rectangle, parallelogram, kite, rhombus are all examples of quadrilateral

Parallelogram is a type of quadrilateral with opposite sides equal and parallel

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
