Question

Sharon is decreasing the size of a diagram of a leaf that is 30 centimeters long by 10 centimeters wide. If the reduced diagram is 4 centimeters wide, how long will it be?

Answer 1

ratio 30:10 = x:4
30/10 =x/4
cross multiply
10x = 120
x = 120/10
x =12

answer:
If the reduced diagram is 4 centimeters wide, long will it be 12

Answer 2

Answer : The length of leaf will be, 12 cm

Step-by-step explanation :

Let the length of leaf be, 'x' cm

Given:

Length of leaf = 30 cm

Width of leaf = 10 cm

Reduced width of leaf = 4 cm

Now we have to determine the reduced length of leaf.

`(30cm)/(10cm)=((x))/(4cm)`

By solving the term 'x', we get the value of x.

`x=(30cm)/(10cm)* 4cm`

`x=12cm`

Thus, the length of leaf will be, 12 cm
