Question

Area=20cm, hight=10cm find the missing side of a right triangle

Answer 1

the missing side of a right triangle is 4
because Area of right triangle = ½ ×b ×h
20 = ½ × b × 10
20 = 5b
b = 20/5
b = 4 cm

Answer 2

Answer:

Step-by-step explanation:

Given:

Area=20cm²

Hight=10cm

Then,

Area of a triangle=½×base×hight

½×b×10

20=5×b

B=4cm

Therefore, breadth=4cm

By phythagoras theorem,

Ab²+bc²=ac²

(Hypotenuse)²=(5)²+(4)²

Hypotenuse=√25+16

Hyp.=√41cm
