Question

the area of right angle triangle is 30 sq.m . it's length is 80m then find its breadth​

Answer 1

Step-by-step explanation:

${ \underline{ \huge{ \bf {AnsWer : }}}}$

We know that,

Area of a ∆ = ½ × base × height

=> 30 = ½ × 80 × height

=> 30 = 40 × height

=> 30/40 = height

=> height = ¾ metres

Note :

height = breadth

length = base

Answer 2

Answer:

3/4

Step-by-step explanation:

Area of a right angle triangle

= 1/2 × length × breadth

= 30 m²

Length of the right angle triangle is 80m.

Therefore,

• 30m² = 1/2 × 80 × breadth
• 30 × 2/80 = breadth
• 60/80 = breadth

3/4 = Breadth
