Question

Q2-The breadth of a rectangular gardeni s2/3 of its length.If its perimeter
is 40 m find its dimensions​

Answer 1

Answer:

$l = 12 \: m \\ b = 8 \: m$

Step-by-step explanation:

$given$

$breadth \: \: of \: \: rectangle \: = \frac{2}{3} l$

$perimeter = 40 \: m$

$we \: \: know \: \: that$

$perimeter \: \: of \: \: a \: \: rectangle = 2(l + b)$

$2(l + \frac{2}{3} l) = 40$

$2 \times \frac{5}{3} l = 40$

$l = 40 \times \frac{1}{2} \times \frac{3}{5}$

$l = 12 \: m$

$b = \frac{2}{3} \times 12$

$b = 8 \: m$

Answer 2

Answer:

Length = 12 and Breadth = 8

Step-by-step explanation:

It is given that bredth is 2/3 of length.

therefore, breadth = 2/3 x L

preimeter of a rectangle = 2( L + B)

40 = 2 ( L + 2/3L)

40/2 = L + 2/3L

20 = (3L + 2L)/ 3

20 X 3 = 5L

60 = 5L

60/5 = L

L= 12m

Bredth = 2/3 of Length

            = 2/3 x 12

            = 2 x 4

            = 8 m
