Answer:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

Let

the breadth =x

the length =6x

$\sf Area=160yard^2$

As we know that in a rectangle

${\boxed{\sf Area=lb}}$

Substitute the values

${:}\longrightarrow$ $\sf x\times 6x=160$

${:}\longrightarrow$ $\sf 6x^2=160$

${:}\longrightarrow$ $\sf x^2={\dfrac {160}{6}}$

${:}\longrightarrow$ $\sf x^2=26.6$

${:}\longrightarrow$ $\sf x=\sqrt {26.6}$

${:}\longrightarrow$ $\sf x=5.1yards$

Length=6\times 5.1=30.6yards
Breadth=5.1yards

Step-by-step explanation:

(hope this helps-you can just put the first sentence...the rest is kinda wordy :P)
