Question

height of a triangle are 10 cm 24 cm and 26 cm find its area

Answer 1

Method 1: Using the formula

A=s(s−a)(s−b)(s−c)−−−−−−−−−−−−−−−−−−√A=s(s−a)(s−b)(s−c)

where, A: Area of the triangle, s: semi-perimeter of triangle,(a,b,c) are the sides of the triangle.

10cm,24cm,26cm10cm,24cm,26cm

Now, s=a+b+c2=10+24+262=30s=a+b+c2=10+24+262=30

A=s(s−a)(s−b)(s−c)−−−−−−−−−−−−−−−−−−√A=s(s−a)(s−b)(s−c)

⇒A=30(30−10)(30−24)(30−26)−−−−−−−−−−−−−−−−−−−−−−−−−√⇒A=30(30−10)(30−24)(30−26)

⇒A=30(20)(6)(4)−−−−−−−−−−−√=36×4×100−−−−−−−−−−√=6×2×10=120⇒A=30(20)(6)(4)=36×4×100=6×2×10=120

A=120sq.cmA=120sq.cm

Method 2: By looking the sides, we can say they form a right angle triangle.

Since, 242+102=262242+102=262

A=12∗base∗heightA=12∗base∗height

A=12×24×10=120sq.cm
