What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 6.5? perimeter = 54 cm, area = 181.25 cm2 perimeter = 54 cm, area = 2,028 cm2 perimeter = 182 cm, area = 2,028 cm2 perimeter = 182 cm, area = 181.25 cm2

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

ratio is 2 : 9

the answer is three

13.5 : 3
