Question

Sarah made a scale drawing of a dinosaur she made the height of the dinosaur 2 1/2 inches the actual height of dinosaurs 9 feet what scale does Sarah use for drawing

Answer 1

Answer:

The scale used by Sarah is 1 to 43.2 inches ( drawing to actual)

Step-by-step explanation:

Here, we want to know the scale used for the drawing of the Dinosaur by sarah.

The actual height of the Dinosaur is 9 feet, but in her drawing she represented the height by 2.5 inches( 2 1/2 is same as 2.5 inches)

Mathematically, we know that 1 foot is 12 inches;

So the actual height of the Dinosaur is 9 * 12 = 108 inches

So practically, what she has done is to represent a height of 108 inches by 2.5 inches

So the scale factor used will be;

108/2.5 = 43.2

The scale used is 1 to 43.2 or simply 1:43.2 to represent the drawing to the actual
