Question

Find the area of a right-angled triangle if its 1. perpendicular =60cm and hypotenuse =61cm​

Answer 1

Step-by-step explanation:

We are given with a right-angled triangle whose measures are

Base =6m

Hypotenuse =6.5m

Using Pythagoras Theorem:

Hypotenuse

= Base

2

+ Perpendicular

2

(6.5)

2

=(6)

2

+ Perpendicular

2

or Perpendicular

2

=42.25−36=6.25

or Perpendicular =2.5m

Now,

Area of a triangle =

×Base×Height

=

×6m×2.5m

=7.5cm
