The width of a rectangle is 15 CM. What is the perimeter of the rectangle, if the length is 3 times the wixth​

Answer 1

$\huge \red{answer}$

$\bf \green{ \underline{given \colon} \: \: width \: = 15cm \:and \: length = 3 \times width = 3 \times 15 = 45cm}$

$\bf \blue{perimeter \:of \: rectangle \: = \boxed{ 2( \: length + width) }} \\ \\ \bf \blue{perimeter \:of \: rectangle \: = 2(45 + 15) } \\ \\ \bf \blue{perimeter \: of \: rectangle = 2(60) = 120cm \: }$

Answer 2

Answer:

The width of a rectangle is 15 cm. If the length is 3 times the width​, then the perimeter of the rectangle is 120 cm.

Step-by-step explanation:

Given: The width of a rectangle = 15 cm

Find the perimeter of the rectangle.

If width = 15 cm

then length = 3 times width = 3 (15) = 45 cm

Formula: The perimeter of the rectangle = 2 (Length + width)

= 2(45 + 15)

= 2(60)

= 120 cm

SO, the perimeter of rectangle is 120 cm.
