The height of the triangle is 60cm, or 20cm+ 40cm.

The equation for area of a triangle is A=1/2bh

Your base is 30 cm height is 20cm.

A=1/2(30)(20)
A=1/2(600)
A=300cm^2

Your answer is 300cm^2

crimeas [40]

Answer:

The rigth answer is, ( 5/2 , -1 )

Step-by-step explanation:

To find the midpoint we use the respective formula:

m = ( x1 + x2 / 2 ,  y1 + y2 / 2 )

We replace:

m = ( 1 + 4/2  ,  3 + (- 5) / 2 )

We solve:

m = ( 5/2 ,  -1 )

What is the value of x in the equation 9/10 (x + 2/3)=4 1/2
garri49 [273]
Get the x variable on one side and the numbers another side.

9/10(x + 2/3) = 4 1/2

Distribute the 9/10 across the x and 2/3.

(9/10)x + 18/30 = 4 1/2

Simplify 18/30 to make our life easier.

(9/10)x + 3/5 = 4 1/2

Subtract 3/5 from each side of the equation.

(9/10)x = 3 9/10

Divide both sides by 9/10.

x = 4 1/3
