Area of a Rectangle when length and perimeter are given Solution

STEP 0: Pre-Calculation Summary
Formula Used
area = (Perimeter*(Length/2))-(Length)^2
A = (P*(l/2))-(l)^2
This formula uses 2 Variables
Variables Used
Perimeter - The perimeter of a figure is the total distance around the edge of the figure. (Measured in Meter)
Length - Length is the measurement or extent of something from end to end. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Perimeter: 20 Meter --> 20 Meter No Conversion Required
Length: 3 Meter --> 3 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
A = (P*(l/2))-(l)^2 --> (20*(3/2))-(3)^2
Evaluating ... ...
A = 21
STEP 3: Convert Result to Output's Unit
21 Square Meter --> No Conversion Required
FINAL ANSWER
21 Square Meter <-- Area
(Calculation completed in 00.016 seconds)
