Question

A rectangle is 3 times as long as it is wide. The perimeter is 60 cm. Find the dimensions of the rectangle. Round to the nearest tenth if necessary.

Answer 1

The given rectangle is 3 times as long as it is wide. The perimeter is known to be 60 cm. Taking this all into account, the dimensions of the rectangle are approximately 7.5 cm in length by 22.5 cm in width, when rounded to the nearest tenth. Hence, if A. 7.5 cm by 22.5 cm is an option, I would say that is the one.

Hope this helps!

Answer 2

Length = 7.5 , Width = 22.5 units .

Explanation:

Given : A rectangle is 3 times as long as it is wide. The perimeter is 60 cm.

To find : Find the dimensions of the rectangle. Round to the nearest tenth if necessary.

Solution : We have given

Let the width of rectangle = x .

According to question

Length of rectangle = 3x

Perimeter of rectangle = 2 (length + width )

Plug the values

60 = 2 ( x + 3x ) .

60 = 2 ( 4x ) .

60 = 8x .

On dividing both sides by 8.

x = 7 .5

Length = 7.5 units

width = 3x = 7.5 *3 = 22.5 units

Therefore, Length = 7.5 , Width = 22.5 units .
