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

Step-by-step explanation:

Area of right angle triangle is = 1/2 × base × height.

so, 30 = 1/2×80 × height

height = 30/40. or 3/4 m
