Perimeter of a rectangle is 40% more than that of a square of side 40 cm. If difference between length and breadth of the rectangle is 8 cm, then find the length of the rectangle.
Perimeter of square = 40 × 4 = 160 cm Perimeter of rectangle = 1.40 × 160 = 224 cm Let, breadth of rectangle = ‘x’ cm So, length of rectangle = ‘x + 8’ cm So, 2(x + x + 8) = 224 Or, 2x + 8 = 112 Or, 2x = 104 Or, x = 52 Length of rectangle = 52 + 8 = 60 cm
16.11 × 9.96 – (238.19 – 64.04 × 2.18) = ?
√483.98 + 120.02 of 119.89 ÷ 59.87 of 29.87 = ?
11.67 × 50.23 + ? = 14.88% of 600.44 + 9.66 × 8.272
9.95% of 1299.99 + 19.95 × 17.05 - 299.99 = ?

?% of [(12.96 × 40.05) + 25.08 × 18.96] = 17.96 × 22.05 + 3.05 × 66.96
20% of 80 × 26% of 65 = ?
(1800.23 ÷ 29.98) + (816.32 ÷ 23.9) + 1634.11 = ?
