Answer:
Area = 5(x + 4y - 6).
Step-by-step explanation:
The area of the whole figure = area of rectangle + area of the triangle
= 10(2y - 3) + 1/2 * 10 * x
= 20y - 30 + 5x
= 5(x + 4y - 6).
As there are two pairs of equal parallel sides, a rectangle has 2 lines of symmetry.
awnser 4x^2 + 20xy + 25y^2
