You would multiply the length by the width.
You could use centimeters which would be 100cm by 34cm = 3400 square cm
The formula for area of a rectanle is A = width x length, therefore A = 34cm x 100cm = 3,400cm2; or A = 0.34m x 1m = 0.34m2
You would use square cm. 1m = 100cm A= 100 cm * 34 cm = 3400 cm2
34cm
Multiply the length of the rectangle by the width. For example: 34cm x 20cm = 680cm2
34cm
It is: 2+15+2+15 = 34cm
2+2+15+15=34cm
13.39 in.
Assuming the object is a rectangle, the perimeter is (2 x 7cm) + (2 x 10 cm) = 34cm
2%g=34cm
34cm + 68cm = 102cm
