Question

the cost of painting a right angle award whose height is 17.5 metre at rupees 4.80 per square metre is rupees 1050 find the base of the triangle ​

Answer 1

Answer:

Area of the triangle = total amount / amount per metre

Area of the triangle = 1050/4.80

Area of the triangle = 218.75

Area of Triangle = (height * base * base) / 2

218.75 * 2 = 17.5 * $base^{2}$

$base^{2}$ = 218.75 * 2 / 17.5

base = $\sqrt{25}$

base = 5

Base of the triangle is 5 metre
