In right angled triangle hypotenuse is the biggest side
1m 100cm
As one side is of 80cm
Then by Pythagoras theorem
(100)²=80²+other side²
10000-6400=other side²
60=other side
Area of right angled triangle =height*base/2
Area =60*80/2
Area =60*40
Area =2400cm²
Cost =2400*250
Cost =600000
1m 100cm
As one side is of 80cm
Then by Pythagoras theorem
(100)²=80²+other side²
10000-6400=other side²
60=other side
Area of right angled triangle =height*base/2
Area =60*80/2
Area =60*40
Area =2400cm²
Cost =2400*250
Cost =600000
