Question

please help me. thanks.

Answer 1

4cm

Step-by-step explanation:

» Concepts

The area of a triangle is how much space is in the triangle. The formula for the area of a triangle is [tex]\frac{1}{2} bh[/tex], where b = base and h = height.

» Application

We're given the area as 10 cm² and the base as 5 cm. Thus, we have to plug these values into the formula to solve for the height.

» Solution

- [tex]10=\frac{1}{2} *5*h[/tex]
- [tex]10=\frac{5}{2}h[/tex]
- [tex]10*2/5=5/2(h)*2/5[/tex]
- [tex]h=4[/tex]

Answer 2

[tex]~~~\text{Area of triangle} = \dfrac 12 \times \text{Base} \times \text{Height}\\\\\implies 10 = \dfrac 12 \times 5 \times w\\\\\implies w =\dfrac{20}5 \\\\\implies w = 4 ~cm[/tex]
