Simple...
you have:

To make this into an improper fraction-->>
1.) Multiply whole number by denominator
2.)Add the number you got plus the numerator
3.) Use the original denominator to finish your improper fraction
Example:

4*9=36
36+4=40

Thus, your answer.
The formula for area of a rectangle is A=lw (length x width). Since the length of the rectangle is 1/2 and the width is 3/4, plug it into the formula and basically just multiply it. :))
The area of the circle is 6,358.5cm²
<h3>Area of the circle</h3>
The formula for calculating the area of a circle is expressed as;
r is the radius = x + y
r = 25 + 20 = 45cm
Substitute the given parameters into the formula to have:
A = 3.14(45)²
A = 6,358.5cm²
Hence the area of the circle is 6,358.5cm²
