Question

A rectangular farm has a length of 300 m and a width of 1/3 of its length. Find its perimeter​

Answer 1

Step-by-step explanation:

l= 300

b= 300*1/3

=100

perimeter of rectangular form

2(l+b)

2(300+100)

400*2

800 meter. Answer

Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

Given:

• length = 300 m
• width = 1/3 of length

To Find:

• Perimeter of the farm

Solution:

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 300 m}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 100 m}\put(-0.5,-0.4){\bf A}\put(-0.5,3.2){\bf D}\put(5.3,-0.4){\bf B}\put(5.3,3.2){\bf C}\end{picture}$ $\implies Width\:of\:the\:farm= \dfrac{1}{3} \times length \\ \implies Width = \dfrac{1}{3\!\!\!\!/_{\:\:1}} \times 300\!\!\!\!\!/^{\:\:100} m \\ \implies Width = 100m \\ \implies Perimeter= 2(length*width) \\ \implies Perimeter = 2(300 + 100) \\ \implies Perimeter = 2(400) \\ \bold{\implies Perimeter = 800m}$

Formula Used:

• Perimeter of rectangle = 2(length*width)
