Agarden is the shape of a rectangle, abcd and a semicircle. ad is the diameter of the semi-circle. carol is going to cover the garden with fertiliser.
a box of fertiliser costs £4.99
carol has been told that one box of fertiliser will cover 12m^2 of the garden
(a) work out the cost of buying enough fertiliser to cover the garden completely

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
