a) 100 sq cm b) 50 sq cm c) 12 sq cm d ) 46 sq cm

Answer 1

Answer:

Step-by-step explanation:

Given that 10 cm is the length of the equal sides. Therefore area of the triangle = ½×a² = ½×10² = ½×10×10 = ½×100 = 50 cm.

Answer 2

Answer:

The area of an isosceles right triangle with one leg 10 cm is 50 sq cm.

Step-by-step explanation:

• For an Isosceles right angle triangle, base and Hight are of equal size.

• Hence the area of the triangle is :        1/2(base × Hight)= 1/2(10×10)

                                                                                                   = 1/2(100)

                                                                                                    = 50 sq cm
