Question

if the area of a triangle is 108 cm square and the height is 12cm . find its base ?​

Answer 1

Answer:

The Height of a triangle is 12 cm

The area of the triangle is 108 cm²

The base of the triangle = ?

we know,

Area of a triangle = $\dfrac{1}{2}$ × base × height .

let, the base be b

ATQ

$\dfrac{1}{2}$ × 12 × b = 108

12 × b = 216

b = $\dfrac{216}{12}$

b = 18

Therefore , The base of the triangle is 18 cm.

Answer 2

Step-by-step explanation:

Let base = x cm

height=12cm

area of triangle= 108cm square

so,

Area of triangle=1/2×base×height

1/2×12 cm× x cm = 108

12×Xcm =216

X cm= 216/12

X cm = 18 cm

So, the base of the triangle is 18cm.

I hope it can help you.
