Answer:

width = w

length= 3w+1

perimeter= 5(3w+1) -45

perimeter = 2(l+b)

5(3w+1) -45 = 2{(3w+1)+w}

15w - 40 = 8w+2

6w = 42

w =7

therefore width = <u>7</u>

length= 3w+1 = <u>22</u>

perimeter= <u>65</u>

A(1,2)

Find slope of line (m)

$\\ \sf\longmapsto m=\dfrac{2-0}{1-0}$

$\\ \sf\longmapsto m=2$

Putting in y=mx+b

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto 2=2(1)+b$

$\\ \sf\longmapsto 2=2+b$

$\\ \sf\longmapsto b=2-2=0$

Equation of the line

$\\ \sf\longmapsto y=2x$
