Question

The expression 1/2bh gives the area of a triangle where b is the base of the triangle and h is the height of the triangle. What is the area of a triangle with a base of 7 cm and a height of 4 cm?

Answer 1

Hey there!

Let's plug these values into the formula.

1/2(7(4))

1/2(28)

14

Therefore, our area would be 14 sq cm.

I hope this helps!

Answer 2

Answer:

The area of a triangle is 14 cm square.

Step-by-step explanation:

Given : The expression $\frac{1}{2} bh$ gives the area of a triangle where b is the base of the triangle and h is the height of the triangle.

To find : What is the area of a triangle with a base of 7 cm and a height of 4 cm?

Solution :

The area of triangle is  $A=\frac{1}{2} bh$

Where,b is the base b=7 cm

and h is the height h=4 cm.

Substitute in the expression,

$A=\frac{1}{2}\times7\times4$

$A=7\times2$

$A=14cm^2$

Therefore, The area of a triangle is 14 cm square.
