Question
The sides of a right-angled triangle are in the ratio
12:13:5. If the total perimeter of the triangle is 120 cm, determine its area.Solution
Perimeter of triangle = 120
12x + 13x + 5x = 120
Or, 30x = 120
So, x = 4
Since, the triangle is right angled, the largest side is the hypotenuse.
So, area of triangle = (1/2) x base x height = (1/2) x 4 x 12 x 4 x 5 = 480 cm2
What approximate value will replace the question mark (?) in the following?
? = 1...
16(17/23)Â + 11(15/46)Â - 15(17/25) =? - 19(13/23)
Find the approximate value of Question mark(?). No need to find the exact value.
(575.86 ÷ 24.03) × (35.96 ÷ 6.03) + √(255.76) = ?
... 5983.987 + 59832.999 – 598.873 = ?
What approximate value will come in place of question (?) in the following given expression? You are not expected to calculate the exact value.
...(?)2 + 4.113 = 25.92 – 32.03
119.922% of 599.90 + (34.78/20.89) × √64.29 × 29.76 ÷ √24.92 = ?2 - 99.92
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exactvalue.)
35.11% of 159.99 + √195.97 ÷ 7.02 = ?
( 1000)1/3  × 10.11 × 4.97 ÷ 10.32 =? – 15.022
