you can divide this picture into 2 pieces, 1 rectangle and 1 triangle.

To find the rectangle, since the opposite sides are equal to each other, the width=6.

the length is 8.
 
to find the area, use the formula

A = lw

A= 8 x 6

A = 48 units square

that's for rectangle.

for the triangle, use the formula

A = h x b / 2

height=10-6 = 4

base is 8 because the opposite sides are equal in rectangle.

Substitute height and base in the formula.

A= 4 x 8 / 2

A= 32/2

A=16 units square

That's the area of triangle.

Now, you can add the area of rectangle and triangle.

Total area = area of rectangle + area of triangle

A = 48 + 16

A = 64 units square
