Maximizing the Area of a Rectangle with Fixed Perimeter. Drag the locators to vary the width of the rectangle and see the effect on its area. For a rectangle with a perimeterof 40, the height is always 20 minus the width. This allows you to reduce the formula for the area, , to .
12 blue marbles.
white marbles is 5X3=15
so blue is
4X3=12.
Using Pythagoras theorem,
.
Hope this helps.
Answer:
Step-by-step explanation:
If you know perimeter, an area you can find by formula
s = P/2
A =
If P ≈ 32.3177 units , then A ≈ 47.9 units²
Answer:
Let 'x' and 'y' be two different numbers.
Leila says that 75% of a number will always be greater than 50% of a number. The inequality that represents this statement is the following:
0.75x > 0.5y
Let x = 100 and y=200. We have that:
0.75(100) > 0.5(200)
75 > 100 ❌ INCORRECT ❌
Given that we found a case in which 75% of a number is not greater than 50% of a number, we can conclude that Leila's claim is incorrect.
