Question

The base of right angled triangle measure 40 cm and its hypotenuse major 50 cm find the area of a triangle

Answer 1

Solutions :-

Given :
Hypotenuse = h = 50 cm
Base = b = 40 cm

Find the perpendicular :-

By Pythagoras theorem,

h² = p² + b²
=> 50² = p² + 40²
=> 50² - 40² = p²
=> 2500 - 1600 = p²
=> 900 = p²
=> √900 = p = 30


Now,
Find the area of triangle :-

Area of triangle = ½ × base × height
= ½ × 40 × 30
= ½ × 1200
= 600 cm²


Answer : Area of triangle = 600 cm²

Answer 2

Answer:

Step-by-step explanation:

Base of triangle = 40cm

Hypotenuse = 50cm

To find height we use Phythagoras theorem

(H) ^2=(P) ^2+(B) ^2

50^2=(P) ^2+40^2

2500 = (P) ^2+ 1600

400 = (P) ^2

P= 20cm

Now area of triangle = 1/2*base*height

= 1/2*40*20

= 400cm^2
