The correct answer is "perimeter=182 cm, area=2028cm²"
original perimeter=2*(8+6)+28 cm
original area=8*6= 48 cm²
You would have to do the old length and width times the scale factor
Multply both of the width's
8 * 6.5 = 52 cm
scale factor: 6 * 6.5 = 39 cm
To get perimeter = 2(length + width)
2(52+39)=182 cm.
So you would have to do length(52 cm) * width(39 cm)
To get 2028 cm^2
Hope this helps!
If at all possible, please share any illustration that comes with any problem you choose to post here.
The dimensions of the original rectangle are 6 cm by 8 cm; thus, the area is (6 cm)(8 cm) = 48 cm^2.
The dimensions of the enlarged rectangle are 6*6.5 cm by 8*6.5 cm, or 39 by 52 cm. The area of this rect. is therefore (39 cm)(52 cm) = 2028 cm^2.
The perimeter of the original rectangle is P = 2(6 cm) + 2(8 cm) = 28 cm.
The perimeter of the enlarged rectangle is P = 2(39) + 2(48) = 174 cm.
