Question

b. We know the area of a triangle is 12 cm2. We also know the height is 6 cm. Find
the base of the triangle (hint: you can use the formula in parta) cm help please

Answer 1

Answer:

The base of traingle is 4cm.

Step-by-step explanation:

Given that the area of triangle is A = 1/2×b×h where b represents base and h is height. So you have to substitute the values into the expressions and solve it :

$area = \frac{1}{2} \times b \times h$

$let \: area = 12,h = 6$

$12 = \frac{1}{2} \times b \times 6$

$12 = 3 \times b$

$12 \div 3 = b$

$b = 4$
