6. ABC is a right-angled triangle. Angle ABC = 90°AC = 25 cm and AB - 24 cm. Calculate the area of aA.ABC |
|
Answer» Answer: The AREA of the triangle is 84 cm². Step-by-step-explanation: NOTE: Refer to the attachment for the diagram. In figure, △ABC is a right-angled triangle. m∟ABC = 90° AC = 25 cm - - - [ Given ] AB = 24 cm We have to find the area of the triangle. In △ABC, m∟ABC = 90° ∴ ( AC )² = ( AB )² + ( BC )² - - [ Pythagoras theorem ] ⇒ ( 25 )² = ( 24 )² + ( BC )² ⇒ 625 = 576 + BC² ⇒ BC² = 625 - 576 ⇒ BC² = 49 ⇒ BC = √49 - - [ Taking SQUARE roots ] ⇒ BC = 7 cm Now, we know that, Area of right-angled triangle = ½ * Base * Height ⇒ A ( △ABC ) = ½ * BC * AB ⇒ A ( △ABC ) = ½ * 7 * 24 ⇒ A ( △ABC ) = 7 * 12 ⇒ A ( △ABC ) = 84 cm² ∴ The area of the triangle is 84 cm². ───────────────────── Alternative Method:In △ABC, AB ( s₁ ) = 24 cm BC ( s₂ ) = 7 cm AC ( s₃ ) = 25 cm Now, we know that, Semi perimeter of triangle = ( Sum of sides ) / 2 ⇒ s ( △ABC ) = ( s₁ + s₂ + s₃ ) / 2 ⇒ s ( △ABC ) = ( 24 + 7 + 25 ) / 2 ⇒ s ( △ABC ) = 56 ÷ 2 ⇒ s ( △ABC ) = 28 cm Now, we know that, Area of triangle = √[ s ( s - s₁ ) ( s - s₂ ) ( s - s₃ ) ] ⇒ A ( △ABC ) = √[ 28 ( 28 - 24 ) ( 28 - 7 ) ( 28 - 25 ) ] ⇒ A ( △ABC ) = √( 28 * 4 * 21 * 3 ) ⇒ A ( △ABC ) = √( 112 * 63 ) ⇒ A ( △ABC ) = √[ ( 16 * 7 ) * ( 9 * 7 ) ] ⇒ A ( △ABC ) = √( 16 * 9 * 7 * 7 ) ⇒ A ( △ABC ) = √( 4 * 4 * 3 * 3 * 7 * 7 ) ⇒ A ( △ABC ) = 4 * 3 * 7 ⇒ A ( △ABC ) = 12 * 7 ⇒ A ( △ABC ) = 84 cm² ∴ The area of the triangle is 84 cm². |

The present ages of Ram and Rehman are in the ratio 8:9. After 5 years, the ratio of their ages will be 9:10 .find there present age |
Answer» Answer :-Given :-
To Find :-
Solution :-Put x in the ratio Now
After 5 years
Also
According to QUESTION :- ⇒ 8x + 5/9x + 5 = 9/10 ⇒ 10 (8x + 5) = 9 (9x + 5) ⇒ 80x + 50 = 81x + 45 ⇒ 50 - 45 = 81x - 80x ⇒ x = 5 Now
Hence, the present ages of Ram and Rehman are 40 and 45 years respectively. |
