Right triangle has an area of 24ft^2. the dimensions of the triangle are increased by a scale factor of 6. what is the area of the new triangle. 48ft^2 72ft^2 144ft^2 864ft^2

Step-by-step explanation:

we know  that

The area of a triangle is equal to

------> equation A

where

b is the base of the triangle

h is the height of the triangle

In this problem the dimensions of the triangle are increased by a scale factor of

so

the new dimensions of the triangle are

The new area of the triangle will be

------> equation B

Substitute equation A in equation B

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

d is the only accurate one
