The area of a square field is 4802 m
^{2}the length of its diagonal is:

A.) 94 m B.) 96 m C.) 98 m D.) None of these Answer: Option 'C'

Let the diagonal be d metres,

Then 1/2 d^{2}= 4802

d^{2}= 9604

d = √9604

d = 98 m - 17. The diagonal of a rhombus are 65 m and 60 m. Its area is:

A.) 1950 Cm ^{3}B.) 1950 Cm ^{2}C.) 1960 Cm ^{2}D.) 1960 Cm ^{3}Answer: Option 'B'

Area of the rhombus = 1/2 d1d2 = ( 1/2 × 65 × 60 ) Cm^{2}

= 65 × 30 = 1950 Cm^{2} - 18. The diagonal of a square is 40 m. The area of the square is:

A.) 800 m ^{2}B.) 800 m ^{3}C.) 750 m ^{2}D.) None of these Answer: Option 'A'

Arear = 1/2 × ( diagonal )^{2}

= ( 1/2 × 40 × 40 )m^{2}

= 1600/2 = 800 m^{2} - 19. The area of the largest triangle that can be inscribed in a semicircle pf rasius r Cm, is:

A.) r ^{3}Cm^{2}B.) r ^{2}Cm^{3}C.) r ^{2}Cm^{2}D.) r ^{3}Cm^{3}Answer: Option 'C'

Area of the largest triangle = (1/2 × 2r × r) Cm^{2}= r^{2}Cm^{2} - 20. Find the area of the sector whose are is making an angle of 90° at the center of a circle of radius 3.2 Cm.

A.) 46.32 Sq.Cm B.) 54.32 Sq.Cm C.) 56.22 Sq.Cm D.) 56.32 Sq.Cm Answer: Option 'D'

Area of the sector = 90/360 × πr^{2}

= 90/360 × 22/7 × 3.2 × 3.2

= (11 × 10.24)/2 = 112.64/2 = 56.32 Sq.Cm
