Question

Area of a triangle is 100 cm .If the height of the triangle is 10 cm, find its base.

Answer 1

Answer:

20 cm

Step-by-step explanation:

we know that, area of triangle = $\frac{1}{2}$ × h × b

⇒  100 = $\frac{1}{2}$ × 10 × b

⇒ 100 = 5b

⇒ 5b = 100

⇒ b = $\frac{100}{5}$ = 20 cm

So, base is 20 cm

Answer 2

Area of triangle=1/2 bh
100cm=1/2 b 10
100cm=5b
b=100/5
b=20cm
