Asquare with an area a^2 of is enlarged to a square with an area of 25a^2. how was the side of the smaller square changed?
a. the side length was increased by 5.
b. the side length was multiplied by 5.
c. the side length was increased by 10.
d. the side length was multiplied by 10.

a square with an area of a² is enlarged to a square with an area of 25a².

The side length of the smaller square was changed when The side length was multiplied by 5.

Area = (1a)² = a²

Area = 1a * 5 = 5a ⇒ (5a)² = 25a²

So, your answer would be B. The side length was multiplied by 5

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
