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
Yes it can its called a scalene triangle
Answer:
x =
Step-by-step explanation:
AC² = AB² + BC²
BC² = 3² + x² = 9 + x²
AB² = 7² + x² = 49 + x²
But AC² = (7 + 3)² = 100
∴ 100 = 49 + x² + 9 + x²
2x² + 58 = 100
x² = 50 - 29 = 21
x =
Answer: B.) 16x^2-22x+6=0
