Surface area : The area of the surface of the figure.
We will find the area of each separate figure, then add them al up:
Triangle: (3*4) / 2 = 6 For 2 triangles the surface area will be 12. Square: 3*3 = 9 Rectangle One: 4*3= 12 Rectangle two: 5 * 3 = 15 Now we add them all up:
12 + 9 +12 + 15 = 48 So the surface area is 48 cm^2
