the perimeter of a basketball court is 102 meters, and length is 6 meters longer than twice the width, what r length and width.
stepladder [879]
Perimeter = 2(l + w)

Thus,

102 = 2(l + w)

l = 6 + 2w

102 = 2( 6 + 2w + w)
102 = 12 + 4w +2 w
102 = 12 + 6w
90 = 6w

Thus, w = 15.

Length = 6 + 2w
= 6 + 30
= 36.

Thus, the length is 36 meters and width is 15 meters.

Nezavi [6.7K]

Hello!

To solve this exercise, let's think a bit and choose the best option for each alternative.

<h2>(a) Karen's desk is about 3...</h2>

Well, a desk with 3mm or 3cm is too small, and with 3km is too big.

In this case, the best option is 3 meters (even though it's big, it's the best option).

<h2>(b) Dan's refrigerator has a mass of 80...</h2>

Usually, a refrigerator is heavy. So the best option is kilograms.

<h2>(c) The bucket holds about 5... of water.​</h2>

5ml of water is too little, it fits in a spoon. The correct option is liters.

Answers:

a. meters

b. kilogr
