Question

a sidewalk is to be made around a rectangular field that has a perimeter of 1,930 feet. the width of field is 20 feet greater than half the length. find dimensions of the field

Answer 1

length = 630

width = 335

Explanation:

p=1930

width = 20+0.5*length

length

perimeter= 2*width + 2*length

2(20+0.5*length)+2*length

40+length+2*length

40+3length=1930

subtract 40

3length=1890

divide by 3

length = 630

plug in length to find width

width = 335
