Question

find the area of isosceles right triangle whose equal side 15 cm

Answer 1

then base and perpendicular will be 15 and 15 cm respectively,


therefore

Area of isosceles triangle=1/2 × 15 × 15,

= 225/2,

=112.5 cm²

Answer 2

here is your answer....

base =15cm=perpendicular=15cm

so area=1/2×base×perpendicular

=1/2×15×15


=112.5cm^2
