Answer:
226 cm^2
Step-by-step explanation:
It’s literally a rectangular prism If you put it together. The side with 2 cm and 11 cm , the surface area is 22 and since this is a rectangular prism, that means there is a second of the same kind. Then you get the larges box, since you know that the top side is 11 and the left side is 7, you multiply that * 2 which you then get 154. You add that up with the side that you solved before so 154 + 44 = 198. You then figure out the left side 7 * 2 * 2 (because there are two of them). 28 + 198 = 226 cm^2.
Answer:
x=22
Step-by-step explanation:
angle RTS = 5x-40 (isosceles triangle)
angle RTS + angle STU = 180 (straight line)
so 5x-40+5x = 180
10x = 220
x=22
Using the 30-deg angle, you can find the side of the parallelogram to be 8 cm.
The height of the parallelogram is 4 cm.
A = 8 cm * 4 cm = 32 cm^2
Answer:
53/56
Step-by-step explanation:
3/8 + 4/7
Get a common denominator of 56
3/6 * 7/7 = 21/56
4/7 *8/8 = 32/56
21/56+ 32/56 = 53/56
