The width of the rectangle is 9 cm and it is 1 cm less than the length. Find the meter and area of the rectangle.

We convert the known width of the rectangle from millimeters to centimeters.

Since 1 cm is 10 mm, we get:

9 mm = 9/10 = 0.9 cm.

Find the length of the rectangle.

Since we know that it is 1 cm wider than the width, we get:

0.9 + 1 = 1.9 cm.

Find the perimeter of the rectangle.

To do this, multiply the sum of the length and width of the rectangle by 2 parts.

We get:

2 * (0.9 + 1.9) = 2 * 2.8 = 5.6 cm.

Determine the area of the rectangle.

To do this, we multiply the length and width of the figure between ourselves.

0.9 * 1.9 = 1.71 cm2

Answer: 5.6 cm, 1.71 cm2
