What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 6.5?

Perimeter is 182 cm,

Area is 2028 cm²

Step-by-step explanation:

Here,

We have a rectangle,

Having length = 8 cm,

Width = 6 cm,

Also, the rectangle is enlarged by the scale factor of 6.5,

Thus, the new length = 6.5 × 8 = 52 cm,

And, new width = 6.5 × 6 = 39 cm,

Now, we know that,

Perimeter of a rectangle = 2 ( length + width )

⇒ Perimeter of the enlarged rectangle = 2 ( 52 + 39 ) = 2 ( 91 ) = 182 cm,

Also, the area of a rectangle = Length × width,

So, the area of the enlarged rectangle = 52 × 39 = 2028 cm²

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
