Question

Find the unknown side length of the rectangle if it's area is 11 m2

Answer 1

since the area of a rectangle is the multiplication of it's length by it's height we can pose a equation that describes the situation:

`(3(2)/(3))*(?)=11`

? is the length of the missing side, now we can solve the equation to find it:

we first convert the mixed number in a fraction

`(((3*3)+2)/(3))*(?)=11`

simplifying

`(11)/(3)*?=11`

now we multiply both sides of the equation by 3/11 to despejate the ?

`?=(3*11)/(11)=3`Then the lenght of the missing side is 3 meters
