Answer:1-12.5 feet, 2-10 feet, 3-13.75 feet, 4-8.125 feet,5-25 feet, 6-20 feet
Step-by-step explanation: All you have to do is break down the scale factor to 1:2.5 and multiply each measurement by 2.5.
An expression means that you may not be able to find a final value, and that it is acceptable to have x in the answer.
The formula for the area of a triangle is A=1/2*b*h
A=1/2*(5x^2+4x)*(2x^2) (distribute the 1/2)
A=(5/2x^2+2x)(2x^2) (distribute the 2x^2)
A=5x^4+4x^3
