Question

find the area of an isosceles triangle whose base is 8 cm and length of each equal side is 5cm​

Answer 1

Step-by-step explanation:

if we draw perpendicular to the base of traingle

the base is divide into half

therefore the base will be 4cm

hence by Pythagorean tripalets the height of the traingle is 3cm

there by using formula

area of traingle = 1/2 × base × height

= 1/2 × 8 × 3

area of traingle = 12 sq. cm

Answer 2

Answer:

12 sq.cm.
