Answer:
48 cm²
Explanation:
Let the breadth be b, then the length is 3b
P = 2(Length + Breadth)
32 = 2(3b + b)
32 = 2(4b)
8b = 32
b = 4
Breadth is 4 cm
Length: 3b = 3(4) = 12 cm
Area of rectangle:
Length × Breadth
12 × 4
48 cm²
The area of a rectangle is its <u>length x width</u>.
The perimeter of a rectangle is its <u>length + length + width + width</u>.
Let's have l stand for length and w for width. A will stand for area and P for perimeter. This gives us:
399 = l x w
80 = 2l + 2w We can divide both sides of this equation by 2 to get <u>40 = l + w</u>.
Now we need to find two numbers whose sum is 40 and product is 399.
Fitting some random numbers in gives us the numbers 19 and 21 for the length and width.
Answer:
negative times A negative is a positive so your answer is 27

Step-by-step explanation:
In the Equation it asks for 3 things; pi (3.14), r (The radius), and h (the height).
In the question, it says that the radius is 1 foot and that the height is 4 feet. From there all you need to do is insert those numbers where it's shown in the equation. This makes the equation go from this:
To this:
From there you follow PEMDAS/GEMDAS. And should have your answer.
