Question

Perimeter of triangle is 60cm.
Its Hypotenuse is 25cm. We have to find the area of the triangle.

Answer 1

Let other two sides be "x"cm

perimeter=sum of all sides

perimeter=AB+BC+CA

60=x+x+25

60=2x+25

60/2=x+25

30=x+25

30-25=x

5cm=x

The area of triangle=1/2×base×height

= 1/2×5×5

area of triangle =12.5cm
