for his project ,a boy needs a piece of wood measuring 0.75 meters long and 0.55 meter wide find the perimeter of the project in centimeters.

Sagot :

First, convert the measurements from m to cm: {note that 100 cm = 1m}
0.75 m = 75 cm 
0.55 m = 55 cm

Assuming that his project is rectangular, the formula for Perimeter is
P = 2L + 2w

P = 2(75cm) + 2(55cm)

P = 150cm + 110cm = 260cm
Perimeter of a Rectangle =2L+2W
=2(0.75m) +2(0.55m)
=2.6 m

Convert 2.6m to cm
In 1cm there are 100 cm
Multiplying 2.6 by 100, you will get 260cm
