Question

If the height of a triangle is

10 c m

and its area is

40 {c m}^{2}

, then the base of the triangle is

6 c m

Options:

A . True

B . False

C . √1463 cm2

D . 24√3 cm2

Answer: Option B
:
B

Area of a triangle = \frac{1}{2} \times b a s e \times h e i g h t = 40

\Rightarrow b a s e = \frac{40 \times 2}{h e i g h t}

\Rightarrow b a s e = \frac{80}{10} = 8 c m
