Question

The expression 2(l + w) is used to calculate the perimeter of a rectangle, where l is length and w is width. If the length is Fraction 2 over 7 unit and the width is Fraction 3 over 7 unit, what is the perimeter of the rectangle in units? (3 points)

Answer 1

LENGTH=2/7

WIDTH= 3/7

Perimeter is 2l+2w

Length= 2/7+ 2/7 is 4/7

Width= 3/7 + 3/7 is 6/7

Answer is 4/7+ 6/7 is 10/7

Answer= 10/7 = 1 3/7
