Question
Calculate the area of the square whose perimeter is
equal to the perimeter of a rectangle which has length 22 cm & breadth 14 cm .Solution
L = 22 cm & B = 14 cm Perimeter of a square = Perimeter of a rectangle 4a =2(L + B) or 4a = 2(22 + 14)= 2 × 36 = 72 So a = 72/4 = 18 Hence area of the square = a 2 = 182  = 324 cm 2Â
[(4 √ (7) + √ (7)) × (7 √ (7) + 6 √ (7))] - 87 = ?
...150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
- What will come in the place of question mark (?) in the given expression?
(24²–45% of 600 + 176 – 32 × 11) = ? 15% of 2400 + (√ 484 – √ 256) = ?
{(81% of 800 + 28 × 4) – 27 × ?} = 11 × 20
((9.77)0- 〖(0.1)〗(-1))/(〖(6/24 )〗(-1) ×(3/2)3+ 〖((-2)/6)〗(-1) ) = ?
...1231 + 1312 + 2113 – 3211 = ?
50% of (22 x 15) + 205 = ?
√441 * 7 – 10% of 250 + ? = 140% of 120
