Question

if the base of a right angle triangle is 8 cm and hypotenuse is 17 cm find its area

Answer 1

area= 8*15/2=60cm^2
area =1/2b*h

Answer 2

Given :-

• Shape = Right Angled Triangle
• Base of Triangle = 8cm
• Hypotenuse of Triangle = 17cm

To Find :-

• Area of the Triangle

Solution :-

❏ Using Pythagoras Theorem :

⟾⠀⠀(H)² = (P)² + (B)²

⟾⠀⠀(17)² = (P)² + (8)²

⟾⠀⠀289 = (P)² + 64

⟾⠀⠀289 - 64 = (P)²

⟾⠀⠀225 = (P)²

⟾⠀⠀√225 = P

⟾⠀⠀25cm = Perpendicular/Height

________________

Now,

⟼⠀Area of Triangle = ½ × Base × Height

⟼⠀Area of Triangle = ½ × 8 × 15

⟼⠀Area of Triangle = 4 × 15

⟼⠀Area of Triangle = 60cm²

Thus, Area of Triangle = 60cm²
