14x - (2x - y) - y
14x + (-1(2x - y)) - y
14x + (-1(2x) - 1(-y)) - y
14x + (-2x + y) - y
14x + 1(-2x + y) - y
14x + 1(-2x) + 1(y) - y
14x - 2x + y - y
14x - 2x
12x

Step-by-step explanation:
The area of a triangle can be found using the formula 
Let 5=h and 7=b
Plug in the values and solve


However, since four of these triangles make up this rhombus, we can multiply the area of one of these triangles by four to find the area of the whole rhombus.


Let the height of each block be x, and no. Of blocks be y
Then,
yx=h
