Question

the breadth of the rectangleis 4/5 of its length if the perimeter is 180 find the area of rectangle

Answer 1

hey dear
here is your answer ✌ ✌

==========

let the length of rectangle be x
perimeter of rectangle = 2 ( length + breadth )
180= 2( x + 4/5x )
90 = 5x +4x /5
450 = 9x
x= 50
so, length is 50
and breadth is 40

area of rectangle = length into breadth
area = (40) (50)
area = 2000


hope it helped ^_^

Answer 2

let length = x and breadth = 4/5x

given

perimeter = 180

perimeter = 2(length+breadth )

180 = 2(x + 4/5x)

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

180= 2(9x/5)

180 = 18x/5

18x = 180x 5

x= 900/18

x = 50.

hence x = length = 50

find breadth

4/5 x 50 = 40.

area = length x breadth = 50 x 40 = 2000.

hope it helps
