Question

A triangle flower bed has a perimeter of 15cm the drawing has a scale of 1:200. What is the perimeter of the actual flower bed

Answer 1

The perimeter of the actual flower bed is 30 meters.

Step-by-step explanation:

If the scale drawing of a triangle flower bed has a perimeter of 15cm and the scale is 1:200, we need to find out the perimeter of the actual flower bed.

First, write the scale as a ratio where the drawing is in the numerator and the actual size is in the denominator:

1/200 = drawing size / actual size

We can solve for the actual size by multiplying the drawing size by the scale factor:

Actual size = drawing size * scale factor

Actual perimeter = 15 cm * 200

Actual perimeter = 3000 cm

Since there are 100 cm in a meter, we divide by 100 to convert centimeters to meters:

Actual perimeter = 3000 cm / 100

Actual perimeter = 30 meters

Thus, the perimeter of the actual flower bed is 30 meters.

Answer 2

300cm

Step-by-step explanation:

scale 1:200 means 1cm on drawing represent 200cm on ground so 15cm will be 15×200 which is 3000cm
