edges. Measure its length and width in centimeters. Take a picture / draw a picture
of the considered object with prime focus on the rectangular surface. Paste / draw
the picture on homework sheet with length and width description. After marking the
dimensions on the picture (length and width), find its perimeter in centimeters. What

Answer 1

Given : rectangular Table

To Find : perimeter in centimeters

effect on the perimeter if we increase the height of the considered object by three feet ​

Solution:

Dimension of top of table

1.2 m and 0.65 m

1 m = 100 cm

1.2 m = 120 m

0.65m = 65 cm

Perimeter = 2(120 + 65)

= 2(185)

= 370 cm

There is no effect on the perimeter if we increase the height of the considered object by three feet ​ as perimeter is  dependent on dimension of top only.
