Question

find the breadth of a rectangular plot of length 45 having perimeter 140m also find its area​

Answer 1

Answer:

Step-by-step explanation:

Perimeter of rectangle = 2(l+b)

140=2(45+b)

140/2=45+b

70-45=b

b=25m.

Area of rectangle = l*b

=45*25

=1125m^2

Answer 2

Step-by-step explanation:

perimeter of rectangle= 2(l+b)

140=2(45+b)

140=90+b

140-90=b

50=b

area of rectangle=lb

=45(50)

2250
