Question

Area of rectangular plot is 2400m length if one and half to its breadth what is perimeter

Answer 1

length=one and half its breadth

l=3/2b

Area of rectangle=2400

lb=2400

(3/2b)b=2400

3/2b^2=2400

b^2=2400(2/3)

b^2=800(2)

b=√1600

b=40m

l=3/2b

l=3/2(40)

l=60m

Perimeter of rectangle = 2(l+b)

=2(60+40)

=2(100)

=200m
