c) 5 times

Step-by-step explanation:

20x5 = 100

120x100 = 12000

b) 12000/600 = 20

c) 15/3 = 5

Answer 2

Answer:

shen's new area will be 1200 ft ^ 2

It will be 2 times the original

Donna should increase the length by 5 times

Step-by-step explanation:

Original length = 40

New length = 30 x 4 = 120

Original width = 20

New width = 20 x 5 = 100

120 x 100 = 12000 ft^2

12000/600 = 20

It will be 20 times larger

For Donna:

ex:

length = 1

width = 2

Area = 2

He wants it to be 15 times 2

Lisa says increase 4 times

2 x 3 = 6

30/6 = 5
