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
