Question

Miranda enlarged a picture twice as shown below, each time using a scale factor of 3.

Answer 1

B,C,E are true !

Step-by-step explanation:

We know that , area of rectangle is :

⇒ $Area = Length(width)$

The original rectangle is 6 by 4  with:

⇒ $Area = 6(4)$

⇒ $Area = 24in^2$

The 1st enlargement = 6*3 by 4*3 So area is :

⇒ $Area = (6(3))(4(3))$

⇒ $Area = 216in^2$

The second enlargement is 18*3 by 12*3 So area is :

⇒ $Area = (18(3))(12(3))$

⇒ $Area = 1944in^2$

A.The area of the first enlargement is 72 square inches.

False it is $216in^2$

B.The area of the second enlargement is 1,944 square inches.

True

C.The area of the second enlargement is (3 squared) squared times the original area.

$\frac{216}{24} =9$  True

D.The area of the second enlargement is 3 times the area of the first enlargement.

$\frac{1944}{24} = 9$  False

E.The ratio of the area of the first enlargement to the area of the original equals the square of the scale factor.

The scale factor is 3,  $3^2 =9$ $\frac{216}{24} =9$

True
