There are 4 triangles with base of 5 and height of 8.4
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 5 x 8.4 = 21 m^2
Multiply by 4 = 21 x 4 = 84 m^2
Area of the base = length x width = 5 x 5 = 25 m^2
Total area = 84 + 25 = 109 m^2
You move the were the decimal to the 2 places to the right and its 3.4%
No, this rel. is not proportional because of the addition involved ("plus 1 lb for each guest").
A proportional rel. features mult. only.
Answer:
6 pounds of fertilizers are needed for garden area of 180 square foot.
Step-by-step explanation:
Let 'x' pounds of fertilizers be needed for 180 square foot garden.
Given:
4 pounds of fertilizer needed for an area of 120 square foot.
The area of the garden given is 180 square foot.
Now, as per question:
4 pounds of fertilizer is equivalent to an area of 120 square foot.
Therefore, 'x' pounds of fertilizer is equivalent to an area of 180 square foot.
Applying proportion and cross multiplying method, we get:
x 4
_ = _
180 120
120x=4 x 180
120x= 720
x = 720
_
120
x=6 LBS
Therefore, 6 pounds of fertilizers are needed for garden area of 180 square foot.
