Question

The base of a right triangle is 18cm and hypotenuse is 30cm. What is the area of the triangle?

Answer 1

Answer:

Step-by-step explanation:

Given for a right -angled triangle,

Base[b] = 18 cm

Height[h] = 30 cm

Therefore AREA = 1/2×b×h

= 1/2×18×30

= 270 cm²

Answer 2

Given :

• Base of right angle triangle= 18cm
• Hypoteneus of right angle triangle = 30cm

To find :

Area of triangle

Formula used :

• Area of triangle = (1/2)×Base × Height

Solution :

Firstly we will find height of right angle triangle by using Pythagoras theorem

Height² + Base² = Hypoteneus²

H² + (18)² = (30)²

H² + 324 = 900

H² = 900-324

H² = 576

H = √576

H = ±24

{ As side can't be negative }

H = +24cm

Area of right angle triangle = (1/2)×Base × Height

Area of right angle triangle = (1/2)×18cm × 24

Area of right angle triangle = 216 cm²

ANSWER :

Area of right angle triangle = 216 cm²
