Question

The area of the rectangle shown is 44 m².
Work out the missing length x.

Answer 1

x = 12 m

Explanation:

the area (A) of a rectangle is calculated as

A = length × width

here A = 44 , then

x × 3
`(3)/(4)` = 44 ( change mixed number to improper fraction )

x ×
`(11)/(3)` = 44 ( multiply both sides by 3 to clear the fraction )

11x = 132 ( divide both sides by 11 )

x = 12 m
