= (18 * 10) cm- (10 X 6) cm
(4x 10) cm?- } (10x 8) cm
= (180 - 30 -- 20 - 40) cm² = 90 cm?
Length of side of square PQRS = 20 cm and PU = 10 cm
Area of the shaded region = Area of square PQRS - Area of AQPU - Area of AQRT
(20 x 20) cm? - Ž (20 x 10) cm - (20 x 10) cm?
= (400 - 100 - 100) cm² = 200 cm?
Exercise 19.2
One side of a parallelogram is 1 m 20 cm. Its distance from the opposite side is 80 cm. Find the area of
ic geometric
the parallelogram.
In the following figures, ABCD is a rectangle and PORS is a square. Find the areas of the
Length of rectangle ABCD = (10 + 8) cm = 18 cm
Breadth of rectangle ABCD = 10 cm
Area of the shaded region
= Area of rectangle ABCD - Area of AEAF - Area of AFDG - Area of ACBE​

Answer 1
