Question

base of right angle triangle is 9 CM and its hypotenuse is 41 cm find its area

Answer 1

Answer:

180 cm²

Step-by-step explanation:

Since, it's a right triangle therefore

Base, B= 9cm

Height, P= ?

Hypotenuse, H= 41cm

By, Pythagoras Theorem:-

H²=P²+B²

or,41²=P²+9²

or,P²=41²-9²

or,P²=1600

or, P=40

Therefore, P=40cm

and we know, triangle's area= 1/2×B×H

Therefore,

(1/2×9×40) cm²

= (20×9)cm²

= 180cm²

Therefore, the area of the triangle is 180cm².

Answer 2

180 cm is the correct answer of this question
