The area shaded in green is 864 cm²
<h3>Similar figures</h3>
Similar figures, corresponding angles are congruent and the sides are ratio of each other. Therefore,
AB / PQ = CD / RS
30 / 10 = 24 / RS
30RS = 240
RS = 240 / 30
RS = 8 cm
let find the height of trapezium PQRS.
AB / PQ = 36 / h
30 / 10 = 36 / h
30h = 360
h = 360 / 30
h = 12 cm
Therefore,
area of the green portion = area of ABCD - area of PQRS
<h3>Area of a trapezium</h3>
Therefore,
area of ABCD = 1 / 2(24 + 30)36 = 1 / 2 (54)36 = 1944 / 2 = 972 cm²
area of PQRS = 1 / 2(10 + 8)12 = 1 / 2(18)12 = 216 / 2 = 108 cm²
Area of the green portion = 972 - 108 = 864 cm²

0.75
Explanation:
Every 1/4 is 25. If you want to calculate them, then you're going to need 1/4 to find 25. In some other cases, 25, can also be written as another decimal. Such as, 4/100.
100/4 is 25. For example:
Woah! You have 3/4 of a dollar. You're really saving up money fast!
This example means that the person has 75 cents.
For an ounce, that would mean 0.04 pounds.
Answer:
3 3/8
Step-by-step explanation:
6 minus 2 5/8 equals 3 3/8
3 3/8 plus 2 5/8 equals 6
Answer:
410.305
Step-by-step explanation:
I forgot how to do standard sorry..
Formula: length · width
2 big rectangles:96 + 96 = 192
(12 × 8) · 2
2 smaller rectangles: 72 + 72 = 144
(6 × 12) · 2
2 small rectangles: 48 + 48 = 96
(6 × 8) · 2
Add all 3 numbers:
192 + 144 + 96 = 432
Your answer is D. 432 cm²
Hope this helps :)
