Question

length of the rectangle whose perimeter is 84m and it exceeds breadth by 4m .find the length

Answer 1

Answer:

Step-by-step explanation:

P=84-4 then be=

2(l+4) =88

L=44-4

L=40

Answer 2

Answer:

Step-by-step explanation:

let breadth=x m

Therfore, length = x+4 m

Perimeter of rectangle=84m

& Perimeter of rectangle = 2 (l+b)

=>84=2 (x+4 +x) m

   84=2 (2x+4)

   2x+4=84÷2  

    2x=42_4

    x=38÷2=19

Hence,The breadth is 19 m and length is 23m
