Perimeter of a rectangle
The formula for calculating the perimeter of a rectangle is expressed as;
P = 2(l +w)
If the smaller rectangle has a length of 4.3 millimeters and width of 4.5 millimeters while a larger rectangle has a length of x millimeters and width of 24.3 millimeters, then;
4.3/x = 4.5/24.3
Cross multiply
4.5x = 104.49
x = 23.22mm
Perimeter of original rectangle = 2(4.3 + 4.5)
Perimeter of original rectangle = 17.6mm
Perimeter of enlarged rectangle = 2(23.22 + 24.3)
Perimeter of enlarged rectangle = 95.04mm
The perimeter of the original rectangle is 17.6mm. The side length of the enlarged rectangle is 23.22mm and the perimeter of the enlarged rectangle is 95.04mm
