Q6 of 41 Page 63

Plot the following points and find out the area of enclosed figures.

O(0, 0), A(0, 7), B(–7, 7), C(–7, 0)

plot points O, A, B and C and join them as shown



As seen in the figure OABC is a rectangle


Area of rectangle = length × breadth


Length = CO = 7 cm


⇒ CO = 7 cm


Breadth = OA = 7 cm


⇒ OA = 7 cm


Area of rectangle = CO × AO


= 7 × 7 = 49 sq. cm
