The length of the rectangle is 3 / 4m wide by 5 / 8m less than the length. find the width of the rectangle and its perimeter.

Let’s calculate what the value of the second dimension of the rectangle will correspond to if we know, based on the conditions of this task, that the first dimension is 5/8 meters larger:

3/4 – 5/8 = 6/8 – 5/8 = 1/8.

Let’s calculate what the value of the perimeter of a given geometric figure will correspond to if we know that the perimeter of a rectangle is calculated as the sum of its measurements multiplied by two:

(3/4 + 1/8) * 2 = 7/4 = 1.75.

Answer: The width of the rectangle is 1/8 meter and its perimeter is 1.75 meters.
