The dimensions are in inches. What is the area of the shape shown, in square centimetres?
- 1000
- 1130
- 1264
Explanation from PART66Online
Split the section into three rectangles. Top flange: 12 x 3 = 36 sq in. Bottom flange: 20 x 5 = 100 sq in. The web's height is the overall 28 in less both flanges, 28 - 3 - 5 = 20 in, so the web is 20 x 3 = 60 sq in. Total: 36 + 100 + 60 = 196 sq in. One square inch is 2.54 x 2.54 = 6.4516 square centimetres, so the area is 196 x 6.4516 = about 1264 square centimetres.
