Question

fin
d the area of isoceles triangle whose equal sides measure 3cm each and third side measure 4cm

Answer 1

S = 5

Area = √(5)(1)(2)(2) = 2√5 cm^2

Answer 2

Answer:

2root5 is the answer of the given question.

Step-by-step explanation:

3 and 3 are equal and base is 4 cm

divide it in 2 equal parts. 2 right angle triangles are formed.with base 2 cm each and hypotenuse 3 cm each.

apply pythagoras theorem. let height be x

2^2+x^2=3^2

4+x^2=9

x^2=5

$\sqrt{5}$

is the height of triangle.

AREA OF TRIANGLE=1/2

$1 \div 2 \times 4 \times \sqrt{5}$

=2root5

hope helpfull to u
