The triangles are similar, they aren't congruent (identical) though as we don't know if they share a common side
Answer:
The answer to your question is 7:6
Step-by-step explanation:
Data
Number of red marbles = 28
Number of green marbles = 30
Number of yellow marbles = 24
Radio = ?
Process
1.- Write the ratio
Red marbles : Yellow marbles
2.- Substitution
28 : 24
3.- Simplification
-Divide both terms by 2
14 : 12
-Divide by two both terms
7 : 6
-It is not possible to simplify more.
A = 864
w = 2/3l
A = lw
Plug in what we know:
864 = l(2/3l)
Multiply:
864 = 2/3l^2
Divide 2/3 to both sides or multiply by its reciprocal, 3/2:
864 * 3/2 = l^2
2592/2 = l^2
1296 = l^2
Find the square root of both sides:
l = 36
So the length of the basement is 36 feet.
