Question

the length of a rectangle is 4m more than the breath if the perimeter of the rectangle is 84m find it's area.​

Answer 1

Step-by-step explanation:

Let to be Length =x+4

Breadth =x

So follow the instructions,

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

then,

Breadth =x =19 m

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