Question

One side of a right-angled triangular scarf is 80 cm and its longest side is 1 m. Find
at the rate of 250 per m2.​

Answer 1

Answer:

ok

IT IS GIVEN THAT THE LONGEST SIDE IS 100cm AND ONE OF THE SIDE IS 80 cm

SO IF WE WANT TO FIND THE AREA WE HAVE TO KNOW ITS PERPENDICULAR AND BASE

SO ONE OF THE SIDE IS LET X

WE WILL COME AT CONCLUSION FROM PYTHAGORAS THAT ... ✓100 POWER TO 2 - 80 POWER TO 2 = 60CM

SO THE AREA = 1/2*60*80 SO AREA IS 2400 CM^ 2

MORE ELSE U CAN FIND BY MULTIPLYING

2.4 * 250=600 RUPEES

Answer 2

In ∆ ABC,

A/c to Pythagoras Theorem

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

(BC)² + (AB)² = (AC)²

(BC)²+(0.8)² = (1)²

(1-0.8)(1+0.8) = (BC)²
