(a) See attachment

(b) Mara's rectangle

Step-by-step explanation:

Given

Mara

Ashton

Solving (a): Draw the rectangles

First, we need to calculate the possible dimension of both rectangles.

Area is calculated as:

For Mara

Possible values of length and width are:

This is so because:

For Ashton

Possible values of length and width are:

This is so because:

Solving (b): Rectangle with bigger area

Mara's rectangle has a bigger area because
