Answer:
3 km
Step-by-step explanation:
The area of a rectangle is given by the formula ...
A = LW
Filling in the given information, we can solve for the length.
1/4 = L·(1/12)
Multiplying by 12, we see that ...
3 = L
The array is 3 kilometers long.
set up an equation for the perimeter
l = length w = width
2l + 2w = 64
set up another equation as you know the length is 3 times the width
w = 3l
subsitute w = 3l into the 2l + 2w = 64
2l + 2(3l) = 64
solve for l
2l + 6l = 64
8l = 64
<em><u>length</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>8</u></em>
subsitute into w = 3l
w = 3(8)
<em><u>width</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em>
