Step-by-step explanation:
Answer:
Simply search for surface area formula for pyramid on goole and plug the numbers into the formula!! Thank you so much!!
Step-by-step explanation:
You would shade 4/6, or 4 parts of the square, since 2/3 is equivalent to 4/6.
The area of one tile is 18 x 18 = 324 square inches.
Convert the dimensions of the room into inches:
5 ft 6 in. = 66 inches.
13 ft = 156 inches.
The area of the room is: 156 x 66 = 10296 square inches.
To find the number of tiles needed, divide the total area of the room by the area of one tile:
10,296 / 324 = 31.78, which means they will need 32 tiles.
This is the concept of transformation, ΔHJK=ΔLMN, from the diagram:
∠H=∠L
∠K=∠N
∠M=∠J
In order to map ΔHJK to ΔLMN, we need to translate K to N and rotate about K until HK lies on the same line containing LN.
