TRUE answer: 144 square feet
So one the triangle face of the pyramid has an area of 27 square feet ( 9 x 6/ 2)

Multiply that by 4 because there are 4 faces of triangles (27 x 4 = 108 square feet)

The area of the square base is 36, we get that by multiplying 6 by 6 (since the square has equal sides.

Add 108 and 36 then you get 144 square feet

ASHA 777 [7]
The Quadrilateral ABCD with coordinates (3, 1), (4, 4), (7, 5), (6, 2) is a rhombus because its length and width are both square root of 10 units and adjacent sides are not perpendicular. This can be seen by plotting the points you can either plot it or by using programs.

I hope this helps, God bless, and have a great day!
