Area is base * height /2 perimeter is u add them all up I think
It costs $3.92 to send all 14 postcards. Or is this a trick question.
Answer:
CE= 32
QS= 14
Step-by-step explanation:
Since the C=R and the E=Q, and the RQ is 16, the CE is 2x that value. (Since the CDE is 2x bigger than RSQ)
You also want to flip the triangles until they are in the same positions as each other so you can analyze it easier
Perimeter = length + length + width + width.
7y-7.5 + 7y-7.5 + 7.5y+8 + 7.5y +8
Combine like terms:
29y+1
The perimeter is 29y + 1 feet
1 ft = 12 inches....so 4 ft = (4 * 12) = 48 inches
ratio is : 48 to 15...or 48/15 or 48:15......which reduces to 16/5 in lowest terms
