Multiply 2 1/4, 1 3/5 and 2 1/3 together! It would be easier to turn these mixed fractions into improper fractions.
Actually, the "slant height" is 4, but the vertical height or "altitude" of the equilateral triangle is not 4
but anyway.....

and the volume, is the area of the triangle, times the length, so, whatever you get for the area of the triangle * 10
X=7
add 3 to both sides.
hope this helps!
3 can be squared twice to get the value of 9. 3x3=9
Answer:

Step-by-step explanation:
Let
L ----> the length of the rectangular garden in feet
w ---> the width of the rectangular garden in feet
step 1
Find the width
we know that
The perimeter of the rectangular garden is


so

Simplify
----> equation A
----> equation B
substitute equation B in equation A and solve for W
Find the value of L

step 2
Find the area
we know that
The area of the rectangular garden is

substitute the values
