Question

12. 12.The length of a Rectangle is 6 cm more than the breadth. If the perimeter of the Rectangle is 80 cm Find the length and breadth of the Rectangle

Answer 1

Answer:

Let i and w be the length and width of the rectangle. We are given:

l=w+6

2(l+w)=60

You have two equations and two unknowns. Solving for l and w gives l = 18 and w = 12. Whence, the area A is given by

A=l⋅w=(18)(12)=216cm2
