Since we know the left side of the rectangle is 13cm, we know the right side adds up to 13cm.. 13cm - 8cm = 5cm.. this is the length of the short leg of the triangle.. from there we can find the area of the rectangle using A = length x height and find the area of the triangle using A = (1/2) x base x height.. add the two areas together and you will get the total area.
