Question

The base of a right triangle is 8cm and hypotenuse is 10cm. Its area will be?​

Answer 1

Explanation:

Given, Right angled triangle

length of base = 8cm

Hypotenuse = 10cm

height ²=10²-8²=100-64=36

Thus height =√36=6cm.

Area of triangle =1/2×base×height

= 1/2×8×6

=8×3

=24 cm²

Answer 2

Answer:

Let the figure be ∆abc,

Let the height be X,

ab=X

BC=8 cm

AC =10 cm

by applying Pythagoras theorem,

height² + base²= hypotenuse ²

x² + 8² = 10²

x²+64=100

x²=100- 64

x²=36

X=√36

X=6

AREA OF THE TRIANGLE =

½× base × height

½×8×6

4×6

24 cm ²
