Arectangular playground has a width of 540 feet and a length of 810 feet. martina makes a scale model of the playground using a scale of 4 cm : 30 ft. what are the dimensions of martina's scale model?

66.67 cm x 108cm.

Step-by-step explanation:

To know that dimensions of Martina's scale model we have to calculate how many centimetres are 540 feet and 810 feet.

We know that 4cm represent 30 feet. Now we need to use the rule of three:

If 4cm represents 30 ft, 500 ft and 810 ft, how many centimetres would be?

Therefore the dimensions, using the scale, is 66.67 cm x 108cm.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
