The length of a rectangle can be found using the following formula: length width
The length of a rectangle that has a width of 2.5 cm and an area of 20.5 cm² is __ cm.

Answer 1

Answer: 8.2 cm

Explanation:

Area of a rectangle = l x w

`A= 25 cm^(2)`

`l= ?`

`w= 2.5 cm`

`25cm^(2) = l(2.5cm)`

• Rearrange the equation to get Length by itself

`(25cm^(2) )/(2.5cm)= l`

`8.2 cm=l`
