P = 2l + 2w
p-2w = 2l
p-2w/2 = l
Substitute the perimeter and you should be able to work it out
24.8 divided by 175 is 0.1417142857142857 or you can round it to 0.142

20= 2(x-4)
20/2= 2(x-4)/2
10= x-4
+4 . +4
14=x
The area of the shaded regions is: 44π
<h3>What is the Area of a Circle?</h3>
Area of a circle where "r" is the radius is determined using the formula: πr².
The figure given has three circles, namely:
- Circle A with radius of 8 cm.
- Circle B with radius of 4 cm.
- Circle C with radius of 2 cm.
The area of the shaded regions = <em>Area of circle A - Area of Circle B + Area of Circle C</em>
Area of Circle A = (π)(8)² = 64π
Area of Circle B = (π)(4)² = 16π
Area of Circle C = (π)(2)² = 4π
Thus:
The area of the shaded regions = 64π - 16π + 4π
The area of the shaded regions = 44π
