3. The area of a rectangular field is 300 m². If its breadth is 15 m find (i)its length and (ii)its perimeter .​

Answer 1

Answer:

A/q

Breadth = 15m

Area = 300 M2

Area = length× breadth

300=15 × length

length = 300/15

length = 20 m

Perimeter= 2(l+b)

=2(15+20)

= 70m

Answer 2

Answer:

LENGHT= 20

PERIMETER= 70

Step-by-step explanation:

given,

breadth= 15m

area= 300 m2

solution=

Area of a rectangle= l*b

300= 15*l

l= 300/15

l=20

perimeter of rectangle= 2(l+b)

      = 2(15+20)

=70
