Answer:
122.5
Step-by-step explanation:
Use the area formula for a trapezoid (attached below as an image):
A = area in sq cm
a = top base
b = bottom base
h = height
Correspond the correct values with the variables:
a = 14
b = 21
h = 7
A = 1/2 * (14 + 21) * 7
A = 1/2*(35)*7
A = 17.5 * 7
A = 122.5 sq cm

Hello There! So your question says you first have to find the the angles of all the triangles , then find there sum ( add them) then do the same for the quadrilaterals, then the hexagons, pentagons and octagons, they are asking if all of them have the same answer or not! Now you need to construct a shape using that sum. And you have to write down the function machine, the number of sides you calculated and number of angles! And then explain that do you think that it is correct!
Wait is there any specific number that we have to use ?
The answer is £140
First you find 20% of 1200 (which is basically 20 times 12) which gives you £240.
You add £240 to £1200 which is £1440
Then you take £300 off £1440 since he already paid the deposit.
That leaves you with £1140
1140 divided by 10 is 114
The answer is financial career...........
Hope I helped
