That mean BE is median because E is mid point divided the line in 2:1, G is centroid, which is 3 → 14.4 1 → 4.8 2 → 9.6 BG = 9.6 Same AD → AG = 2/3 × 10.8 = 7.2 Area of ∆ABG = 1/2 × 7.2 × 9.6 = 34.56 Area of ∆ ABC = 3 × ∆ABG Area of ∆ ABC = 3 × 34.56 ∆ABC = 103.68 cm2
78.89 × 81.03 – (16.83)² + 8.33% of 9602.87 = ? – 50.23
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
4261 + 8234 + 2913 + 8217 + 6283 + 4172 =?
25% of 400 + 3 × 102 = ?2
104 × 21 ÷ 13 + ? % of 300 = 320 + 22
1549.8 ÷ 8.2 + 65.6 × 55 = (? × 4) + (42 × 30.5)
√( (664+ √(136+ √(59+ √(21+ √(7+ √81) ) ) ) ) ) = ?
[4(1/3) + 4(1/4)] × 24 – 62 = ?2
(5/7) of (7/11) of (3/5) of 52% of 4400 = ? - (44)2 + (50)2 - (62% of 1750) - (188 ÷ 9.4)
