Arectangle has a width of 12 ft and a length of 4 ft. what is the effect on the perimeter when the dimensions are multiplied by 6? the perimeter is increased by a factor of 6. the perimeter is increased by a factor of 24. the perimeter is increased by a factor of 96. the perimeter is increased by a factor of 192.

Option A is the answer.

Explanation:

The length is given as = 12 feet

The width is given as = 4 feet

So, perimeter =

=

Perimeter = 32 feet

when the dimensions are multiplied by 6, so length becomes = feet

width becomes= feet

So, new perimeter becomes=

= 192 feet

Dividing the new perimeter with old one =

Hence, The perimeter is increased by a factor of 6.  

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
