Question

find a base of a triangle where area is 42 cm and height is 12 CM​

Answer 1

Step-by-step explanation:

Given: Area of △=42 cm

Given: Area of △=42 cm 2

Given: Area of △=42 cm 2

Given: Area of △=42 cm 2 Base of △=12 cm

Given: Area of △=42 cm 2 Base of △=12 cmWe know that,

Given: Area of △=42 cm 2 Base of △=12 cmWe know that,Area of △=

Given: Area of △=42 cm 2 Base of △=12 cmWe know that,Area of △= 2

Given: Area of △=42 cm 2 Base of △=12 cmWe know that,Area of △= 21

Given: Area of △=42 cm 2 Base of △=12 cmWe know that,Area of △= 21

Given: Area of △=42 cm 2 Base of △=12 cmWe know that,Area of △= 21 ×Base×Altitude

Given: Area of △=42 cm 2 Base of △=12 cmWe know that,Area of △= 21 ×Base×Altitude⇒42=

Given: Area of △=42 cm 2 Base of △=12 cmWe know that,Area of △= 21 ×Base×Altitude⇒42= 2

Given: Area of △=42 cm 2 Base of △=12 cmWe know that,Area of △= 21 ×Base×Altitude⇒42= 21

×12×Altitude

×12×Altitude⇒Altitude=

×12×Altitude⇒Altitude= 12

×12×Altitude⇒Altitude= 1242×2

×12×Altitude⇒Altitude= 1242×2

×12×Altitude⇒Altitude= 1242×2

×12×Altitude⇒Altitude= 1242×2 ⇒Altitude=7cm
