Question

the area of a right angle triangle is 30sq.m. the length is 80cm. the find its breadth. ​

Answer 1

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

We know that,

Area of a ∆ = ½ × base × height

=> 30 = ½ × 80 × height

=> 30 = 0.40 × height

=> 30/0.40 = height

=> height = 75cm.

Note :

➔ height = breadth

➔ length = base

Answer 2

$\huge\mathcal{Given}$The area of a right angle triangle is 30sq.m. the length is 80cm. the find its breadth.

$\huge\fbox\red{Solútiôn}$

Area of a ∆ = ½ × base × height

• Area of a ∆ = ½ × base × height=> 30 = ½ × 80 × height

• Area of a ∆ = ½ × base × height=> 30 = ½ × 80 × height=> 30 = 0.40 × height

• Area of a ∆ = ½ × base × height=> 30 = ½ × 80 × height=> 30 = 0.40 × height=> 30/0.40 = height

• Area of a ∆ = ½ × base × height=> 30 = ½ × 80 × height=> 30 = 0.40 × height=> 30/0.40 = height=> height = 75cm.

$\huge\mathcal\red{Note}$

➡ height = breadth

➡length = base
