Question

The base and height of right angled triangle is 8cm And 11cm then what is its area

Answer 1

Answer:

Step-by-step explanation:

To calculate the length of a side on a right-angled triangle when you know the sizes of the other two, you need to use Pythagoras' Theorem. Pythagoras' Theorem says that, in a right angled triangle: The square of the hypotenuse is equal to the sum of the squares on the

two sides.

To calculate the length of a side on a right-angled triangle when you know the sizes of the other two, you need to use Pythagoras' Theorem.

Pythagoras' Theorem says that, in a right angled triangle:

The square of the hypotenuse is equal to the sum of the squares on the other two sides.

We can write this more simply as :

{a^2} = {b^2} + {c^2}

Calculating the length of the hypotenuse

Question

Use Pythagoras' Theorem to calculate the length of the hypotenuse. Give your answer to 2 decimal places.

rectangle 4 x 7 x X

Hide answer

Write the equation x^{2} = 7^{2} + 4^{2}

Square the lengths you know x^{2} = 49 + 16

Add together x^{2} = 65

Find the square root x = \sqrt {65}

x = 8.06 (to\,2\,d.p.)

Answer 2

44cm

Given:-

• Base of Right angled triangle = 8cm
• Height of right angled triangle = 11 cm

To find:-

• Area of right angled triangle

Solution:-

$\bigstar\;\sf Area\; of \;right \;angled\; triangle = \dfrac{1}{2} \times base \times height \\ \\ :\implies\sf \dfrac{1}{2} \times 8 \times 11 \\ \\ :\implies\sf \cancel{ \dfrac{88}{2}} \\ \\ :\implies\bf 44\;cm$

Additional Information:-

• If three side are given of a triangle then heron formula is used to find area of given triangle.

• And if given traingle is equilateral and its base and height are given then [$\frac{1}{2}$ × b × h] is used to find the area of given triangle.
