Question

Find the area of a triangle; whose sides
(i) 10 cm, 24 cm and 26 cm​

Answer 1

Answer:

120 cm ^2

Step-by-step explanation:

Sides of ∆ are

a = 10 cm

b = 24 cm

c = 26 cm

S = (a + b + c)/2 = (10 + 24 + 26)/2

= 60/2 = 30

after this the pictures above shown is the solution

                         

Answer 2

Step-by-step explanation:

Area by Heron's formula =

s = a + b + c / 2

s = 60/2

s = 30

Area = √s(s-a)(s-b)(s-c)

= √30(30-10)(30-24)(30-26)

= √30 X 20 X 6 X 4

= √14400

Area = 120cm^2
