Question

3 students are taken to a park to draw the picture of a boy standing in front of a

tree. The actual height of the tree and the boy are 15 feet and 5 feet respectively.

If following are the height of the tree and the boy in the drawings of the 3

students, find out whose drawing can be called ‘Up to the scale’?

Student Height of the tree

(cm)

Height of the boy

(cm)

Student A 10 4

Student B 13.5 4.5

Student C 14.2 4.8

​

Answer 1

Answer:

if up to the scale means of perfect measure, then option

B IS CORRECT

Step-by-step explanation:

here actual height of tree, u1=15 feets

and actual height of boy,u2=5 feets

ratio of u1 and u2

15/5=3:1

now this ratio if is equal to the measures of the tree and the boy's height then that would be Up to the scale( if it means of perfect measure)

Let tree height in drawing be v1 and of boy be v2

Checking for:

(I)10/4=3:1

2.5:1≠3:1

Clearly it is not upto scale

(ii)13.5/4.5=3:1

3:1=3:1

therefore this kids drawing is up to scale

hence proved students B's drawing is UP TO SCALE
