The surface area if the figure is all of the areas added together.Find all the areas by splitting the shape into different pieces:We can first start with the triangle.The triangle area is: 1/2(b)(h)1/2(4)(3)2(3)Triangle Area: 6Now, we can find the area of the rectangles. You can find this by multiplying base × height:3 · 4 = 124 · 1.5 = 6Now add all your areas to get your surface area:12 + 6 + 6 = 24 cm²Answer:24 cm²
