rectangles and triangles come in many shapes. You need to pin down some of the properties a little more exactly.
Is the base of the triangle the same as one of the sides of the rectangle?
Anyway, label the sides of your figure, and add them up. They must sum to 46. Can't be that hard.
A shape ABCDE is made up of an isosceles triangle and a rectangle. The perimeter of ABCDE is 46cm.
