= 2 • (21 - 1)
Do the subtraction inside the parentheses.
= 2 • 20
= 40
Step-by-step explanation:
given,velocity = 5 m/s
and distance=12×1000=12000m

Answer:
Let the width of the garden =x meter
Then length=(x+4) meter
Half perimeter =36 m
So perimeter of garden =(2×36)=72 meters
According to the question
⇒2(l+b)=72
⇒2(x+x+4)=72
⇒2x+2x+4=74⇒4x=64⇒x=16 meters
Hence,the width of the garden =16 meters
The length of the garden =(16+4)=20 meters
