Answer 1

Answer:

sorry the numbers are not same , but its the same format question

Step-by-step explanation:

Ratio of Length : Width = 32 : 12 (Given)

Simplify by dividing by 4:

Ratio of Length : Width = 8 : 3

Define x:

Let x be the constant ratio

Ratio of Length : Width = 8x : 3x

Solve x:

8x = 56

x = 7

Find the width:

width = 3x = 3(7) = 21 cm

Answer: The width is 21 cm

Answer 2

Step-by-step explanation:

let it increased by a factor x

then given that 10cm becomes 15 cm

hence 10.x = 15

=> x = 15/10 = 1.5

now for shorer side increase = 6cm.x = 6cm × 1.5cm = 9 cm
