Detailed Solution for Test: Geometry- 2 - Question 5

Test: Geometry- 2 - Question 6

Two circles of an equal radii are drawn, without any overlap, in a semicircle of radius 2 cm. If these are the largest possible circles that the semicircle can accommodate, what is the radius (in cm) of each of the circles?

Detailed Solution for Test: Geometry- 2 - Question 6

Test: Geometry- 2 - Question 7

PQRS is a Trapezzium, in which PQ is Parralel to RS, and PQ = 3 (RS) . The diagnol of the Trapezzium intersect each other at X, then the ratio of,  ar ( ∆ PXQ)  : ar ( ∆ RXS)  is?

Detailed Solution for Test: Geometry- 2 - Question 7

In ∆ PXQ and ∆ RXS

=> angle P = angle R

    angle Q  =  angle S 

:- ∆ PXQ  ~ ∆ RXS  ( AA similarity rule)  

ar ( ∆ PXQ) /  ar ( ∆ RXS) = ( PQ / RS) ^ 2 

 =  ( 3 / 1 ) ^ 2

=     9 / 1 

Therefore,  ar ( ∆ PXQ) :  ar          ( ∆ RXS) 

=   9:1

Test: Geometry- 2 - Question 8

Detailed Solution for Test: Geometry- 2 - Question 12

Test: Geometry- 2 - Question 13

What is the area of the triangle in which two of its medians 9 cm and 12 cm long intersect at the right angles?

Detailed Solution for Test: Geometry- 2 - Question 13

Test: Geometry- 2 - Question 14

Four horses are tethered at four comers of a square plot of side 14 m so that the adjacent horses can just reach one another. There is a small circular pond of area 20 m2 at the centre. Find the ungrazed area.

Detailed Solution for Test: Geometry- 2 - Question 14

Total area of plot = 14 * 14 = 196m2
Horses can graze in quarter circle of radius = 7m
Grazed area = 4 * (pie r2)/4 = 154 m2
Area of plot when horses cannot reach = (196 - 154) = 42m2
Ungrazed area = 42 - 20 = 22m2

Test: Geometry- 2 - Question 15

Two sides of a triangle are 4 and 5. Then, for the area of the triangle, which one of the following bounds is the sharpest?

Detailed Solution for Test: Geometry- 2 - Question 15

Let AB = 4 and BC = 5 and AB is perpendicular to BC

then Area = 1/2 AB . AC = 1/2 . 4.5 = 10
