Question

Stacy is making a scale drawing of her backyard. There is a triangular-shaped flower garden with dimensions of 6feet, 8feet, and 10ft. She is using the scale 1inch=2feet. Find the perimeter of the flower garden in her drawing.

Answer 1

The perimeter of the flower garden in the drawing is
`12\ in`

Explanation:

we know that

The scale drawing is equal to
`(1)/(2)(in)/(ft)`

To find the dimensions in the drawing multiply the actual dimensions by the scale drawing

so

`(6\ ft)*(1)/(2)(in)/(ft)=3\ in`

`(8\ ft)*(1)/(2)(in)/(ft)=4\ in`

`(10\ ft)*(1)/(2)(in)/(ft)=5\ in`

The perimeter of the flower garden in the drawing is equal to

`P=3+4+5=12\ in`
