Question

Find the area of a
right triangle whose two sides are
24cm and 7cm and the perimeter is
56cm. ​

Answer 1

Answer:

84 sq.cm

Step-by-step explanation:

Area = 1/ 2 x base x height

 Here base length = 24 cm and height= 7 cm

Thus, area = 1/ 2 x 24 x 7= 84 sq.cm

Answer 2

Answer:84

Step-by-step explanation:

Given:

sides=[24,7,x]cm

24+7+x=56

31+x=56

x=56-31

x=25

heron's formula;root(s)(s-a)(s-b)(s-c)

root(56\2)(56\2-24)(56\2-7)(56\2-25)

root(28)(4)(21)(3)

root(112)(63)

4root(7)*3root(7)

12*7

84
