Answer: 75 square

Explanation:

Width is X

Length is 3x

Every rectangle has 2 equal widths x 2 equal lengths

Perimeter is 2x + 2(3x) = 40
X = 5

Width is now 5in

Length is now 15in

Area is 75in^2

Half of a perimeter is length + width, which equals to 20in

4x = 20, CX = 5
= 75 sq

The distance will be the diffrence between the x-co ordinates.

\sf Distance = 1 - (-2\dfrac{1}{2})

             \sf =1+\dfrac{5}{2}\\\\= \dfrac{2}{2}+\dfrac{5}{2}\\\\=\dfrac{7}{2}\\\\=3\dfrac{1}{2}
