Answer 1

Let the length be x

then the breath will be x+4m

2(l+b)=84m

2(x+x+4)=84m

x+x+4=84÷2

2x+4=42m

2x=42-4

2x=38m

x=38÷2

x=19m

Length=19m

Breadth=19+4=23m

Answer 2

$\huge\red{\bf{hello}♡}$

GIVEN:-

Perimeter of rectangle=84m

Let the Length be =x+4

Breadth =x

araa of rectangle= 2(L+B)

→2(L+B)=84

2(x+x+4)=84

2(2x+4)=84

2x+4=84/2

2x+4=42

2x=42-4

2x=38

x=38/2

x=19

Breadth =x =19 m

Length=x+4= 19+4=23m
