The length and width of a rectangle are 5 feet and 2 feet, respectively a similar rectangle has a width of 8 feet. What is the length of the second rectangle?

2:8::5:?

2/8=5/W
W=20

The answer is 20

Step by Step explanation
1. 8x5(the width of the 2nd rectangle x the length of the 1st rectangle)
2. 8x5=40 than divide by 2 =20

The length and width of a rectangle are 4 feet and 3 feet, respectively.

A similar rectangle has a width of 9 feet.

What is the length of the second rectangle?

help pls

To find the length of the second rectangle, we can use the concept of similar figures. Similar figures have proportional side lengths.

In the given information, the length of the first rectangle is 5 feet and the width is 2 feet.

We can set up a proportion using the corresponding sides of the two rectangles:

Length of the first rectangle / Width of the first rectangle = Length of the second rectangle / Width of the second rectangle

Plugging in the values we know:

5 feet / 2 feet = Length of the second rectangle / 8 feet

To find the length of the second rectangle, we can cross-multiply and solve for the unknown variable:

5 feet * 8 feet = 2 feet * Length of the second rectangle

40 square feet = 2 feet * Length of the second rectangle

Dividing both sides by 2 feet:

Length of the second rectangle = 40 square feet / 2 feet

Simplifying:

Length of the second rectangle = 20 feet

Therefore, the length of the second rectangle is 20 feet.
