The length of a rectangle is 3 centimeters more than 3 times the width. if the perimeter of the rectangle is 46 centimeters, find the dimensions of the rectangle. length = 5 cm; width = 18 cm length = 18 cm; width = 5 cm length = 13 cm; width = 8 cm length = 13 cm; width = 5 cm

length = 18 cm; width = 5 cm

Step-by-step explanation:

Given : The length of a rectangle is 3 centimeters more than 3 times the width.

Let x be the width of the rectangle , then the length will be  3x+3.

We know that ,

Perimeter = 2( length+ width) = 2(3x+3+x)=2(4x+3)=8x+6

Since the perimeter of rectangle is 46 centimeters.

Then, we have

i.e. Width of rectangle = 5 cm

Length = 3(5)+3=15+3=18 cm

Hence, the correct answer is : length = 18 cm; width = 5 cm
