Assume L=1.5W, where W=width, L= Length of the triangle.
Therefore,
Perimeter (P) = 2(W+L) = 2(W+1.5W) = 2(2.5W) = 5W=20 => W=20/5 = 4 in
Then, L=1.5W = 1.5*4 = 6 in
Area, A= L*W = 6*4 = 24 in^2

Answer:
<u>3 cm</u>
Step-by-step explanation:
The formula for the volume of a pyramid is :
- V =
<u>Given</u>
- Volume = 60 cm³
- Base Area = 12 cm x 5 cm = 60 cm²
<u>Solving</u>
- 60 = 60 x h x 1/3
- 60 = 20h
- h = 60/20 = <u>3 cm</u>
The answer is 340, not super good at math so dont know what scientific notation is but there you go
Step-by-step explanation:
