Question

The breadth of a rectangle 4 a pon 5 of it's length. lf the perimeter is 180 m,then find the area of rectangle​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

let the length be x

breadth = 4x/5

according to question

perimeter of square = 2(l+b)

2(x+4x/5) = 180

2(5x+4x/5) = 180

2*9x/5 = 180

18x/5 =180

X= 180*5/18

x= 10*5

x=50

length = X = 50 m

breadth = 4x*5= 4*50/5 = 4*10= 40m

Area of rectangle = length * breadth

40m * 50m

2000m^2

the answer upper is wrong because when you will multiply 40 to 50 we will get 2000 not 200 but you marked him / her as brainliest
