Question

The length of a rectangle is 10 m more than its breadth. Express its perimeter as an expression in x.

Answer 1

Answer:

The perimeter of an object is the sum of all it's lengths. So in this problem, 80m = side1 + side2 + side3 + side4. Now a rectangle has 2 sets of equal length sides. And we are told that the length is 10m more than it's breadth.
