Arectangular field has an area of 1,764 m^2. the width of the field is 13 m more than the length. what is the perimeter of the field?

Let the length of the field be x, then width = x + 13
x(x + 13) = 1764
x^2 + 13x - 1764 = 0
(x - 36)(x + 49) = 0
x = 36

Therefore, length is 36 m and width = 36 + 13 = 49
Perimeter = 2(length + width) = 2(36 + 49) = 2(85) = 170 m

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
