Question

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?

Answer 1

length = 12 feet

Explanation:

since the rectangles are similar then the ratios of corresponding sides are in proportion.

let x be the length of the second rectangle, then

`(x)/(4)` =
`(9)/(3)` = 3 ( multiply both sides by 4 )

x = 12

the length of the second rectangle is 12 feet]
