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:
37.7 ft
Step-by-step explanation:
you have to to find the area of the figure first then multiply by the height
Answer:
1000 m³
Step-by-step explanation:
The base of a cube is just a square.
The area of a square is , where l is the length.
Since we know the area of the base (the square) we can find l easily.
Now that we know the length of the sides, we have to take note that a cube has side lengths that are all congruent.
This means the height of the cube is also 10m.
Since the volume of a cube is represented as , where l is the length, we can substitute 10 in as to find it's total volume.
So the volume of this cube is 1000 m³.
Hope this helped!
Answer:
the number is 7
Step-by-step explanation:
the equation is
4x-6 = 22
add 6 to both sides
4x =28
divide both sides by 4
x=7
