Question

the are of a rectangle is 200 m sq if its length is 20m,find the breadth and perimeter​

Answer 1

Answer:

Breadth = 10 m , Perimeter = 60 m

Step-by-step explanation:

Area  = Length X Breadth

So 200 sq m = 20 m x b

b = 10 m

Perimeter = 2(Length + Breadth)

Perimeter  = 2(20 + 10) m

= 2(30)m

= 60 m

Answer 2

area of rectangle = 200m²

lenth = 20m

to find breadth

area of rectangle = l× b

200m²= 20m x b.

200m² /20m =b

b = 10m

to find perimeter

perimeter of rectangle = 2(l+b)

= 2 ( 20m + 10m)

= 2× 30m

= 60m
