There are two triangles.

Area of a triangle = 1/2 x 10 x 9 = 45 square in.

45 x 2 = 90 square inches

One side is 9 x 9 = 81 square inches.

One side ix 10 x 9 = 90 square inches.

One side = 9 x 13.5 = 121.5 square inches.

Total surface area = 90 + 81 + 90 + 121.5 = 382.5 square inches.

subtract one value to the other to see how many valued we have in between
-7 - (-2) = 5
7-2=5
Both of the lines XY AND ZW have 5 units or points in between them.
Length = 5 units
They are congruent since XY = ZW in length and essentially are the same line but at different points
