If the length of each side of an equilateral triangle were increased by 50 percent, what would be the percent increase in the area?

The area increase by 225%

Step-by-step explanation:

attachment of a triangle

The area of a triangle equilateral is calculated with the next formula:

A=

=

= *3

h=

h=

replacing in the A equation:

A=

A=

Now each side increse by 50% ⇒ a=1.5a

A=

A=

A=2.25 *

It means that the area incrase by 225%

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
