Question

The length of a rectangle is$6m$ more than the breadth. If the perimeter of a rectangle $60m$. Find the length and breadth of the rectangle

Answer 1

Let the breadth of the rectangle $=x$

Length$=x+6$

Perimeter$=60m$

$$\begin{gathered} 2(x+6+x)=60 \\ 2(2x+6)=60 \\ 4x+12=60 \\ 4x=60-12 \\ 4x=48 \\ x=\frac{48}{4} \\ x=12 \end{gathered}$$

Length$=12$

breadth $=x+6=12+6=18$
