Question

the breadth of a rectangular field is half of its length. if the length is 100 m. find the area and perimeter of the field.​

Answer 1

Answer:

100

2 = 50

B=50

L= 100

A= l×b = 100×50=5000m2

P= 2× (l+b) = 2×(100+50)= 300m

Answer 2

Step-by-step explanation:

Let the length of and breadth of the rectangular field be 'l' and 'b'

$b = \frac{1}{2} l \\ l = 2b$

and it is given that l = 100 m

By substituting l value in the above equation, we get b = 50 m

Area of rectangle = l × b

= 100 × 50

= 5000 m^2

Perimeter of rectangle = 2( l + b)

= 2( 100 + 50)

= 300 m
