    2W + 2(W + 3.1) = 15.8
    2W + 2W + 6.2 = 15.8
    4W + 6.2 = 15.8
    4W = 9.6
    W = 2.4

    Perimeter
    2.4 + 2.4 + (2.4 + 3.1) + (2.4 + 3.1) = 15.8

    Answer:

    w is 4.8 meters

    Step-by-step explanation:

    -perimeter is 15.8 m so all the sides of the rectangle adds up to 15.8.

    – a rectangle has 2 sets of equal sides.

    -first, do 3.1 times 2 to get the length of the first set of equal sides. This equals to 6.2.

    -now 15.8 – 6.2 = 9.6 meters

    – 9.6 divided by 2 to find the width, as well as the measurements of the second set of equal sides.

    the width, w, is 4.8 meters.
