12.806248474865697
187 sq. inches (area for a rectangle= length x width
Using Pythagoras' theorem it is 26 inches in length
the answer is 48 in2
it's four thirds as long as it is wide.
The area of rectangle is : 21.0
Add the length and the width; Double the answer; Job done.
Simply add length plus width (8+6=14) and add the total to itself (14+14=28). Done!
15 inches (solved with the help of Pythagoras' theorem)
P = 2(length) + 2(width) P = 2(12 inches) + 2(10 inches) P = 44 inches
