Hey!
The formula of direct variation is y = kx. So we know that p = kr^2
Hint: after it says varies, it's basically the equal sign.
so we can set it up
56 = 4^2k
56=16k
now we want k alone so we have to divide 16 on both sides
k=3.5
We can now solve for p like it asks
p = 3.5*6^2
p=126
There's your answer!
Hope this helps!
Answer: 5
Step-by-step explanation: 5×2+=10 so 5 but you can also mix it up
Answer:
The length of each side of square is 5ft.
Step-by-step explanation:
Given:
A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft squared.
The area of the triangle is 7.5ft squared.
Now, to find the length of each side of square.
Now, we need to get the area of the square first:
Area of combined figure - area of triangle = area of square.
32.5 ft squared - 7.5 ft squared = 25 ft squared.
So, area of square = 25 ft squared.
Now, by putting the formula for getting the length of each side:
Let the side = a.
Area of square = 25 ft squared
Area of square = a²
Using square root both sides we get:
So, the side = 5 ft.
Therefore, the length of each side of square is 5ft.
Answer:
First try getting the formula for all the shapes and from then on just plug it in.

Hope that helps :/
Area of square =6*6= 36 cm^2
Area of trapezoid =1/2( base1+base2)*height
base 1=7
base2=21-6=15
height=6
Area of trapezoid =1/2( 7+15)*6= 66
whole area = area of square + area of trapezoid= 36+66=102
