Question
The area of a square is 40 sq. cm more than the area of
a rectangle of length 20 cm and breadth 18 cm. What will be the area of incircle of the square? MTSolution
The area of rectangle = l × b = 20 × 18 = 360 sq. cm The area of square = 360 + 40 = 400 sq. cm The side of square = √400 = 20 cm Radius of incircle of a square = side = 20/2 = 10 cm
- Determine the final value of this expression:
(1/5) of {5β΄ - 24 Γ 14 + 12 Γ 18 - 10.5 of 10Β²} 3% of 842 ÷ 2% of 421 = ?
β225 + 27 Γ 10 + ? = 320
- Determine the value of βpβ if p = β529 + β1444
45 % of 180 + β144 * 8 = ?2 Β + 70 % of 80
Determine the value of 'p' in following expression:
720 Γ· 9 + 640 Γ· 16 - p = β121 X 5 + 6Β²- 7?2 = β20.25 Γ 10 + β16 + 32
- What will come in place of the question mark (?) in the following questions?
(2β΄ + 6Β²) Γ· 2 = ? 18(1/3) + 9(2/3) β 10(1/3) = 1(2/3) + ?
