Question

the area of a rectangular field is equal to 300 square meters. its perimeter is equal to 70 meters. find the length and width of this rectangle.

Answer 1

Length of the Rectangular Field is 20 m and Width is 15 m:

Let L: Length of the Rectangle
W: Width of Rectangle
Area of Rectangular Field : Length x Width = LxW =300---(i)
Perimeter = 2(L+W)=70
(L+W)=35
L=35-W
Put this value in Eq (i), you will get following equation :
x2-35x+300 =0 After solving this equation, L=20 and W=15
