Question

7. If the base of a right angled triangle is 8 cm and the hypotenuse is 17 cm. finds its area​

Answer 1

Answer:

60cm²

Step-by-step explanation:

hypotenuse is 17 and base is 8

by using Pythagoras theorem

(17)²=(8)²+(height)²

height=15

area of triangle= 1/2 into base into height

1/2into 8 into15

4into15

area = 60cm²

Answer 2

Answer:

base =8cm , hy=17cm

By phythagoras theorem,

hy²=l²+b²

17²=l²+8²

289=l²+64

l=√225

l=15cm

So ,l=15cm , b=8cm

Area= 1/2 * 15 * 8

=60cm²
