Answer: The area of the square is 64 square inches and the area of the new rectangle is 60 square inches. The square's area is 4 inches larger than the rectangle.
Step-by-step explanation: If a side length of the square measures 8 inches, then its area can be calculated as follows;
Area = L x W
The length and the width both measure 8 inches (all sides of a square are equal in length).
Area = 8 x 8
Area = 64
Also, the the new rectangle is formed by increasing the width of the square by 2 inches (that is 8 + 2 = 10), and decreasing the length by 2 inches (that is 8 - 2 = 6). The area of the new rectangle is calculated as follows;
Area = L x W
Area = 10 x 6
Area = 60
Therefore the area of the square is 64 square inches and the area of the rectangle is 60 square inches. The area of the square is 4 inches larger than that of the rectangle.
The formula for the perimeter is 2L + 2W.
Since we know that L=10+W, we can substitute this into the equation.
2(10+W) +2W=124
20+2W + 2W=124
4W +20 = 124
4W=104
W=26
Therefore, the width is 26 inches.
All straight lines equal 180 degrees that problem equals 210.
Answer:
20π ft
Step-by-step explanation:
To find the circumference of the circle given its area, first find its radius.
Substitute given area into the formula:
100π= πr²
Divide both sides by π:
100= r²
Square root both sides:
r= 10 ft
Since we have found the value of the radius, we can substitute r= 10 into the formula above to find the circumference.
Circumference of circle
= 2(π)(10)
= 20π ft
