the breadth of a rectangular Garden is 2/3 of its length. if its perimeter is 40m find its dimensions
Answers
Answer:
length is 12
width is 8
Step-by-step explanation:
x is the length...so width is 2x/3
thus perimeter is:
2X (x + 2x/3) =40
5x/3= 20
5x=60
so, x =12
length is 12
width is 2/3 of 12 which is 8
Answer:
Length = 12cm
Width = 8cm
Step-by-step explanation:
Let the length be x
Let the width be 2/3x
Perimeter = 2 (l+b)
Length = 2 (x+2/3x) = 40
= x + 2/3x = 40/2
= x + 2/3x = 20
= x/1 + 2/3x = 20
LCM = 3
= 3x + 2x = 20
______
3
= 3x + 2x = 20 x 3
= 5x = 60
= x = 60/5
= x = 12
Width = 2/3 of 12
= 2/3 × 12
= 8
Therefore, The required Length = 12cm,
The required Width = 8cm
Hope this helps you!!!
