Answer:

25 2/15

Explanation:

A = length x width

width is 4 1/6

35 = 4 1/6 x length

solve for length

divide both sides by 4 1/6

35 divided by 4 1/6 or multiply 35 x 6/25 (reciprocal)

210/25

8 10/25 = 8 2/5 is the length

to find perimeter 2xlength + 2xwidth

2 x 4 1/6 + 2 x 8 2/5 = 2 x 25/6 + 2 x 42/5 = 50/6 + 84/5

convert to common denominator and add

use 30 as common denominator

250/30 + 504/30= 754/30

25 4/30 or 25 2/15
