Question

are rectangular field has a an area 28800 in length is twice as long as it with what is the length of its wide and find cost of fencing it it it is 46.5 per metre​

Answer 1

Answer:

let the width be x.

therefore its length will be 2x.

Area of rectangle = length × breadth

\begin{lgathered}28800 = 2 {x }^{2} \\ {x }^{2} = 14400 \\ x = \sqrt{14400} \\ x = 120\end{lgathered}

28800=2x

x

=14400

x=

14400

x=120
