Question

Mark wants to create a scale drawing of the poster shown below:

A rectangle is shown. The length of the rectangle is labeled 4 centimeters. The width of the rectangle is labeled 10 centimeters.

What are the dimensions of the poster at one-half its current size?
2 cm by 10 cm
2 cm by 5 cm
8 cm by 20 cm
8 cm by 5 cm

Answer 1

Just divide both by 2.
4/2=2
10/2=5
so the answer is
2cm by 5cm

Answer 2

you would add all the sides since it's dimensions which could mean the perimeter then divide it by 2
4+4 = 8 cm /2 = 4 cm /2 = 2 cm
10+10= 20 cm /2 = 10 cm /2 = 5 cm

the right answer is B, 2 cm by 5 cm
