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

Let

the breadth =x

the length =6x

$\sf Area=160yard^2$

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

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

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

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

Oksanka [162]

Answer:

let t = number of three-point shots

let f = number of free throw shots

Step-by-step explanation:

3t + 1f = 23 (number of shots multiplied by their point value)

substitution method: t = 9 - f

3(9 - f) + f = 23

27 - 3f + f = 23

-2f = -4

f = 2

find 't': t + 2 = 9

t = 7
