Question

in the rectangle the breadth is one third of its length. the perimeter is 80m. find the length and breadth​

Answer 1

Answer:

length= 30m. and breadth=10m

Step-by-step explanation:

let the length be x

and breadth be 1/3x

perimeter is 80 m

perimeter of rectangle =2(L+B)

80 = 2(x+1/3x)

80 =2 (3x+x/3)

80 /2 = 4x/3

40 = 4x/3

x =40*3/4

x = 10*3

x= 30 m

Length (L). =. x=30 m

Breadth (B) = 1/3* 30 =10m
