A rectangle has a perimeter of 66 meters and a height of 14.2 meters. What is the length of the base?

Hey there! I'm happy to help!

The perimeter is the distance around the rectangle. You have used the word height, but I will replace it with the word width because the word height is usually used with 3D shapes.

If W is the width and the length is L, the formula for the perimeter is 2W+2L=P.

We can plug in the numbers we already have to solve for L, the length of our base.

2(14.2)+2L=66

28.4+2L=66

We subtract 28.4 from both sides.

2L=37.6

We divide both sides by 2.

L=18.8

The length of the base is 18.8 meters.

Have a wonderful day!

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
