In the given figure (not drawn to scale), ABCD is a rectangle. ED = 16 cm, FG = FC = 8 cm, BF = 20 cm and FG is perpendicular to BC. If CD is half of AD, then find the area of the shaded region (in cm2).
In the given figure, state whether the triangles are congruent and choose the correct order.
AYes, ΔABC ≅ ΔDCE
BNo, they are not congruent
CYes, ΔDCE ≅ ΔCAB
DYes, ΔDEC ≅ ΔCAB
Study the statements and choose the correct option.
Statement 1 : Rajan had money which was enough to buy 30 books at the rate of Rs 20 per book. If the price of each book is increased to Rs 25, then Rajan can buy 24 books with the same amount of money.
Statement 2 : Since in the above case, the value of one variable increases and the value of the other decreases, the problem is based on the application of inverse variation.
AStatement 1 is true and statement 2 is false.
BStatement 1 is false and statement 2 is true.
CBoth statement 1 and 2 are false.
DBoth statement 1 and 2 are true.
statement 2 is also correct as price increases then no of book decreases for same amount implying inverse variation, suggested statement 2 as false is incorrect.
