Answer:
Step-by-step explanation:
From Chapter 9 and from your earlier classes, you know that:
Area of a triangle = × base × height.
area of Δ ABC is given by. × base × height = × 12 × 5 cm2, i.e., 30 cm2. Note that we could also take 5 cm as the base and 12 cm as height

Answer:
Let the sides of ∆ ABC be a= 40m, b = 32cm, 24m.
- To find area we must use Heron's formula because we are not given the height.
- Using Heron's formula, we get:-
- semi perimeter = a+b+c/2.
- =40+32+24/2.
- = 48m.
- s-a=48-40=8m.
- s-b= 48-32= 16m.
