Area of ||gm and triangle_1

The median of a triangle divides it into two

• triangles of equal area

• congruent triangles

• right triangles

• isosceles triangles

The figure obtained by joining the mid-points of the adjacent sides of a rectangle of sides 8 cm and 6 cm is

• a rectangle of area 24 cm2

• a square of area 25 cm2

• a trapezium of area 24 cm2

• a rhombus of area 24 cm2

In Fig. 9.4, the area of parallelogram ABCD is :

• AB × BM

• BC × BN

• DC × DL

• AD × DL

In Fig. 9.5, if parallelogram ABCD and rectangle ABEF are of equal area, then :

• Perimeter of ABCD = Perimeter of ABEM

• Perimeter of ABCD < Perimeter of ABEM

• Perimeter of ABCD > Perimeter of ABEM

The mid-point of the sides of a triangle along with any of the vertices as the fourth

point make a parallelogram of area equal to

Two parallelograms are on equal bases and between the same parallels. The ratio of their areas is

• 1 : 2

• 1 : 1

• 2 : 1

• 3 : 1

ABCD is a quadrilateral whose diagonal AC divides it into two parts, equal in area,

then ABCD

• is a rectangle

• is always a rhombus

• is a parallelogram

• need not be any of (A), (B) or (C)

If a triangle and a parallelogram are on the same base and between same parallels, then the ratio of the area of the triangle to the area of parallelogram is

• 1 : 3

• 1 : 2

• 3 : 1

• 1 : 4

ABCD is a trapezium with parallel sides AB = a cm and DC = b cm (Fig. 9.6). E

and F are the mid-points of the non-parallel sides. The ratio of ar (ABFE) and

ar (EFCD) is

• a : b

• (3a + b) : (a + 3b)

• (a + 3b) : (3a + b)

• (2a + b) : (3a + b)

The area of quadrilateral ABCD in the given

figure is

• 57 cm2

• 108 cm2

• 114 cm2

• 195 cm2
