Question

A Rectangular field is four times as long as its breath. if its area is 1600 Msquare find the Perimeter. Plz show the solving part too not only the answer

Answer 1

Answer:

perimeter of rectangle=2(l+b)

Area of rectangle=l × b

Area =1600 sq meter

also length= 4× breadth

4b^2=1600

b^2=400

b=20

length×breadth= 1600

length×20=1600

length= 80

Perimeter=2(80+20)

=2(100)

=200 meters
