Question

one side of a right-angled triangular scarf is 80cm and its longest side is 1m .Find its cost at rate of 250rs per mSq.

Answer 1

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
