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%

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
