Answer:
Total Surface Area = 1120 yd squared
Explanation:
Surface Area = Total Area of each shape.
This prism is made from the following shapes
2 Triangles = 120 yd squared
3 Rectangles = 1000 yd squared
120 + 1000 = 1120 yd squared
- The Area of a Rectangle is L x W
- The Area of a Triangle is Base x Height / 2
OR 1/2 Base x Height
Let's start with your two Triangles:
8 x 15 = 120 | 120 ÷ 2 = 60 yd squared
60 yd squared is the Area of 1 Triangle you have two triangles, 60 yd squared x 2 = 120yd squared
Let's move onto the Rectangles:
1 Rectangle Area 25 x 15 = 375 yd squared
1 Rectangle Area 25 x 17 = 425 yd squared
1 Rectangle Area 25 x 8 = 200 yd squared
375 + 425 + 200 = 1000 yd squared
