Answer:
13/18
Step-by-step explanation:
Well the formula for Volume of a Rectangular Prism is {Length x Width x Height = Volume}
So we know 18.5 x 9 x Length = 2,830.5
Divide by 18.5 and 9 and you are left with the length of 17 xD
Answer:
D. 15cm2
Step-by-step explanation:
To find the area of a triangle, you multiply the base (10cm) and height of the triangle (3cm) and divide that by 2. So 10×3=30. Then, you need to divide this by 2. Since 30 is an even number, you won't get a decimal. So 30/2=15. And dont forget your units!
