src="file:///C:/Users/ashut/AppData/Local/Temp/msohtmlclip1/01/clip_image002.png" alt="" width="6" height="20" /> . AB =6cm. AC = 8cm. A square DEFG is drawn inside the triangle whose side FG is coincident with BC. E and D lie on the sides AB and AC respectively. FIND OUT Length of the side of the square (cm).Solution
∠A = 90° AB = 6cm AC =8cm BC = 10 cm When a square is formed inside the triangle and one side of the square coincides with the hypotenuse The length of side of the square = ABC/ a² +b² +c² =(6×8×10)/(36+64+48) = 480/148 = 120/37cm

Evaluate: 320 − {18 + 4 × (21 − 9)}
Simplify: 72 ÷ 6 × 3 − 8 + 4
118 × 6 + 13 + 83 = ?
Simplify the following expression:
  (400 +175) ² - (400 – 175) ² / (400 × 175)
150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
(75 + 0.25 × 10) × 4 = ?2 - 14
26% of 650 + 15% of 660 – 26% of 450 = ?
115% of 40 + 3 × 4 = ? × 11 – 8
