Sagot :

a.

A rectangle has opposite side equal to each other . Therefore, it can be drawn below

perimeter = x + x + 4x + 4x

b.

The relationship between herman rectanngle base and height can be express below

[tex]\begin{gathered} 4\text{ times the height=base} \\ \text{let } \\ \text{height}=x \\ 4\times x=base \\ \text{base}=4x \end{gathered}[/tex]

c.

perimeter = 60 feet

[tex]\begin{gathered} \text{perimeter}=x+x+4x+4x \\ 60=10x \\ x=\frac{60}{10} \\ x=6 \\ \\ \text{Base}=4x=4\times6=24\text{ f}eet \\ \text{height}=x=6\text{ f}eet \end{gathered}[/tex]
