Arectangle has an area of 16ft squared, every dimension is multiplied by a scale factor, and the new rectangle has an areaof 64 ft squared, what was the scale factor?

Scale factor is 2

Step-by-step explanation:

A rectangle has an area of 16ft²

That is

            Length₁ x Breadth₁ =  16 ft²

Every dimension is multiplied by a scale factor, let the scale factor be s.

New dimensions are

                  Length₂ = s x Length₁

                  Breadth₂ = s x Breadth₁

New area is given by

                 Area = Length₂ x Breadth₂ = s x Length₁ x s x Breadth₁

                 Area = s² x Length₁ x Breadth₁

                 64 = s² x 16

                  s² = 4

                  s = 2

So scale factor is 2

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

1 ?

step-by-step explanation:

u said 1+1+1+1+1+1+1+1+1+1+1+1*0 so ur adding 1 but then multiplying by 0 so its 0 but then u said 1*0+1 so now ur adding 1 so the answer is juan ?
