## TOPICS RELATED TO PERIMETER & AREA

### What is the formula for perimeter of area?

The method for the perimeter of a rectangle is regularly written as p = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. the place of a 2-dimensional figure describes the amount of surface the shape covers. you measure area in rectangular units of a set length.

### What is difference between perimeter and area?

Perimeter refers back to the outline that surrounds a closed parent. .region represents the distance occupied with the aid of the object. ... as the fringe is measured in linear units, it measures simplest one measurement i.e. duration of the object. while, inside the case of place, dimensions are worried i.e. length and width of the object.
