It asks for area. area for rectangle is length * width. and triangle is 1/2 * base * height

The long side area has sides of 10 and 6. So area for that side is:
10 * 6 = 60
(I got the 6 from using the height of other side. they are same height)

area of other side is the area of rectangle and triangle added together.
area rectangle = 8 * 6 = 48
area triangle = 1/2 * 3 * 8 = 12

area side = 12 + 48 = 60

area 2 sides = 60 + 60 = 120
