Question

Shawn Drew a triangle that had a width of 4.2 inchesand a length of 8.1 in inches find the perimeter of the rectangle

Answer 1

20.4 inches, because you would have to do 8.1 + 8.1 because there are two long sides then add 4.2 to that because of the width. so technically youd only have to add 3 numbers.

ANSWER---20.4
