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:

Breadth = 3/4

Step-by-step explanation:

Area of a right angle triangle

= 1/2 × length × breadth

= 30 m²

therefore,

breadth = area × 2/ length

= 30 × 2/ 80

= 60/80

= 3/4 m
