Question

ABC is a right angled triangle with hypotenuse AC=25cm and BC=24cm. Calculate the area of the triangle

Answer 1

Answer:

hypotenuse = 25, side = 24

length of 3rd side =v25^2-24^2

=v49x1=7cm

Area = bh/2 = 24x7/2=84cm2. Ans

Answer 2

Answer:

84 cm²

Step-by-step explanation

By pythagoras theorem

Hypotenuse²=Base²+Height²

AC²=BC²+AB²

AB²=AC²- BC²

AB²=(25)²-(24)²

AB²=625-576

AB²=49

√AB²=√49

AB=7

Area of triangle=1/2×base×height

Area of triangle=1/2×7×24

                         =7×12

                        =84 cm²
