The perimeter of the original rectangle is 16 feet. A small rectangle has a length of 6. 2 feet and width of 1. 8 feet. A larger
ankoles [38]

The perimeter of the enlarged rectangle is 32 ft and the width of the larger rectangle is 3.6 ft.

<h3>What is perimeter of plane?</h3>

The measure of the boundary of a plane or shape is called its perimeter. The perimeter of a plane or shape is the sum of all the sides.

A small rectangle has a length of 6.2 feet and width of 1.8 feet. The parameter of this triangle is,

P_s=6.2+1.8\\P_s=8\rm\; ft

The small rectangle has a length of 6.2 and the larger rectangle has a length of 12.4 feet. Thus the scale factor of enlargement is,

r=\dfrac{12.4}{6.2}\\r=2

The perimeter of the original rectangle is 16 feet and scale factor is 2. Thus, the perimeter of the enlarged rectangle is,

P_l=2\times16\\P_l=32\rm\; ft

The small rectangle has width of 1.8 feet and scale factor is 2. Thus, the width of the larger rectangle is,

w_l=1.8\times2\\w_1=3.6\rm\; ft

Hence, the perimeter of the enlarged rectangle is 32 ft and the width of the larger rectangle is 3.6 ft.
