Question

find the area of a right angled triangle if its base is 4 and hypotenuse is 5​

Answer 1

Area = 6................

Answer 2

Answer:

6 cm ²

Step-by-step explanation:

Hypotenuse of triangle = 5

Base of triangle = 4

By using Pythagoras theorem

(Hypotenuse)²=(Base)²+(Height )²

$(5) {}^{2} =(4) {}^{2} + (x) {}^{2} \\ 25 = 16 + (x) {}^{2} \\ 25 - 16 = (x) {}^{2} \\ 9 = (x) {}^{2} \\ x = \sqrt{9 } \\ x = 3$

Area of equilateral triangle =

$1 \div 2 \times base \times height$

$1 \div 2 \times 3 \times 4 \\ 6$

hence the area of triangle is 6
