QuestioN:-
- If the base of a right-angled triangle is 6 cm and the hypotenuse is 10 cm, find its area.
AnsweR: Area of triangle is 24 cm²
________________________________
Step by step explanation:-
Given :-
- Base of triangle is 6 cm
- Hypotenuse of triangle is 10cm
To find :- Area of triangle
Concept:-
- First we have to find height of triangle means perpendicular by using Pythagoras theorem
- Then we use Formula of area because we need area of triangle according to question.
SolutioN:-
We know that Pythagoras theorem is
◆(Perpendicular)² + (base)² = ( Hypotenuse)²
- Now substitute the values in this formula.
➟ (Perpendicular)² + (6)² = (10)²
➟ (Perpendicular)² + 36 = 100
➟ (Perpendicular)² = 100 - 36
➟ (Perpendicular)² = 64
➟ Perpendicular = √64
➟ Perpendicular = 8 cm
As we all know perpendicular is also known as height.
Then , we want the area of triangle, So formula for area is :-
◆Area = 1/2 × base × height
Put the values of base = 6 cm and height = 10 cm for area
⇝ Area = 1/2 × 6 × 8
⇝ Area = 6 × 4
⇝ Area = 24 cm²
Answer
- Area of triangle = 24 cm²
Given
- The base of a right-angled triangle is 6 cm and the hypotenuse is 10 cm
To Find
- Area of the right triangle
Formula Used
- Pythagoras Theorem
- (Opp.)² + (Adj.)² = (Hyp.)²
- Area of the triangle
- ¹/₂ × Base × Height
Solution
Find attachment .
Apply Pythagoras theorem for finding height , x .
⇒ x² + 6² = 10²
⇒ x² + 36 = 100
⇒ x² = 100 - 36
⇒ x² = 64
⇒ x = 8 cm
So , height , x = 8 cm
Now , Apply area of triangle .
⇒ ¹/₂ × Base × Height
⇒ ¹/₂ × 6 × 8
⇒ 3 × 8
⇒ 24 cm²
So , Area of triangle is 24 cm² ←
