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

Answer:

height = (20 + 40) cm\\  = 60cm \\ area =  \frac{1}{2}  \times b \times h \\  =  \frac{1}{2 }  \times30 \times 60 \\   = \frac{1800}{2}  \\  area= 900 {cm}^{2}

Step-by-step explanation:

Hope that this is helpful .

Answer:

Step-by-step explanation:

2p/2 = 2x+7

1) 2x+7 -x - 5 =

width = x + 2

2) 2p/2 = 21 in

x + 5 + x + 2 = 21

2x = 14

x = 7

lenght = 7 + 5 = 12 in

width = 7 + 2 = 9 in

3 )

A = (x+5)(x+2)

4)

A = 12 x 9 = 108

Help me plz. I dont understand.
Ahat [919]
For this, you would use simultaneous equations.

w=walnuts
a=almonds

3w+6a=51
5w+4a=55

Find a way to make one of the unknowns equal. since we are trying to work out the price of a pound of walnuts, I am going to make a equal on each side to leave us with w. This leaves us with:

15w+12a=165
6w+12a=102

Then take them away to leave w:

9w=163

Then solve:

w=163/9
= 18.11111111...

Then round it to 2 decimal places as the measurement is currency.

So 1 pound of walnuts equals $18.11
