Answer 2

Answer:

Given,

Hypotenuse of right angle triangle = 61cm

Perpendicular of right angle triangle = 60cm

to find :-

Area of right angle triangle.

$\huge\sf\underline{solution}$

as it was right angle triangle :-

(hypotenuse)² = (base)²+(perpendicular)²

(61cm)² = (base)² + (60cm)²

3721cm² = base² + 3600cm²

base² = 3721cm² - 3600cm²

= 121 cm²

= (11cm)²

base = 11cm

area of right angle triangle = $\sf\dfrac{1}{2}$ × base × perpendicular

= 1/2 × 11cm × 60cm

= 11cm × 30cm

= 330cm²
