Answer:
The area of one rectangle is 15 cm²
Step-by-step explanation:
The given parameters are;
The area of the square = 64 cm²
The length of the rectangles = 5 cm
The formula for the area of a square = (Side length)² = S²
Therefore, whereby the side length of the given square = S, we have;
Area of the square = 64 = S × S = S²
S = √(64 cm²) = 8 cm
The side length of the square = 8 cm
The perimeter of a square = The length of the string = Side length × 4 = 8 cm × 4 = 32 cm
∴ The perimeter of a square = The length of the string = 32 cm
The length of the string = The perimeter of the two congruent rectangle = 32 cm
Therefore;
The perimeter of each rectangle = 32/2 cm = 16 cm
Given that the length, L of the side of each rectangle is L = 5 cm, we have;
The perimeter of a rectangle = 2 × L + 2 × W
Where;
W = The width
The perimeter of the rectangle = 16 = 2 × 5 + 2 × W
2 × W = 16 - 2 × 5 = 6
W = 6/2 = 3
W = 3 cm
The width, W, of each rectangle is W = 3 cm
The area of one rectangle = W × L = 3 cm × 5 cm = 15 cm²
The area of one rectangle = 15 cm².
Answer:
390
Step-by-step explanation:
A bakery makes 260 donuts in 4 hours At this rate the bakery can make 390 donuts in 6 hours .
To find out how many donuts the bakery can make in 6 hours at the given rate, you can use a proportion based on the information provided:
Let's denote the number of donuts made as "x" in 6 hours.
The rate of making donuts is 260 donuts in 4 hours.
So, the rate can be expressed as: 260 donuts / 4 hours = 65 donuts/hour.
Now, you can set up a proportion:
260 donuts / 4 hours = x donuts / 6 hours
Cross-multiply and solve for x:
260 * 6 = 4 * x
1560 = 4x
Divide both sides by 4:
x = 1560 / 4
x = 390
So, at this rate, the bakery can make 390 donuts in 6 hours .
