Question

If (s-a)=5cm (s-b)=10cm and (s-c)=1cm find the value of s where a,b and c are sides of the triangle.

Answer 1

Step-by-step explanation:

s= a+b+c/2

s= 5+10+1/2

s=16/2

s=8 cm

= s(s-a)(s-b)(s-c)

= 8(8-5)(8-10)(8-1)

=8×3×2×7

=2×2×2×3×1×2×1×7×1

=2×2×2×1 root under 3×7

=8 root under 21 cm square
