Question

Th are of four square is drawn on a length and breath of a rectangle is 82 cm2. What is the area of square in cm2

Answer 1

Let length of the rectangle be l and the breadth be b.

Area of square with side l = l^2

Area of square with side b = b^2

l^2 + b^2 + l^2 + b^2 = 82

2(l^2 + b^2) = 82

l^2 + b^2 = 41

Assuming l>b and values be integral,

l = 5

b = 4

So area of rectangle = lb = 5*4 = 20
