(ii) it’s area.

Answer 1

Answer:

breadth= 30

area = 90×30 = 2700m²

Step-by-step explanation:

perimeter of rectangle = 2 (l +b)

perimeter = 240m = 2(90+ x)

: 240 = 180 + 2x

2x = 240-180

2x = 60

x = 60/2

x= 30

Area of rectangle is = l × b = 90×30

area = 2700 m²

Answer 2

Answer:

I) breadth=30m

ii) area = 1200m

Step-by-step explanation:

i) perimeter of rectangle= 240m

length of rectangle=90 m

let the breadth be x

p= 2×(l+b)

240m=2*(90m+x)

240/2=90+x

120m=90+x

120-90= x

30m=x

ii) length=90m

breath=30m

area = l*b

=90*30

=2700m
