Question 940428: How do I calculate the length of the shorter of the two sides of a rectangle which has an area of 18.86m2 and a perimeter of 21.00 m? Found 2 solutions by laoman, MathTherapy:Answer by laoman(51) (Show Source): You can put this solution on YOUR website! For a rectangle, Area = length * breadth
Perimeter = 2(length + breadth)
Let l rep. length, breadth reo. w
From statement Area, l*w=18.86 eqn1
and Perimeter, 2(l+w)=21
expanding
2*l+2*w=21 ----eqn2
Solving eqn1 and eqn2 simultaneously
