Answer:
B
Step-by-step explanation:
( point E)
202 ft^2
The lateral area is the area of all the sides except the base. So you find the area of the triangles (16), then the left rectangle (80), then the right rectangle (90). Finally you add them together.
16+16+80+90=202
51.44÷80%=64. 3$$
Because (100-20=80%)
Answer:
125%
Step-by-step explanation:
In this kind of question, we could choose any arbitrary value for the length of the side of the square.
Let’s say the square is 10m in length, a 50% increase in the length means we add 5 to the original length making the new length to be 15m.
The area of a square is L^2
The former area is 10 * 10 = 100 while the new area is 15 * 15 = 225
The percentage increase is calculated as follows:
We simply subtract the old from the new to yield 225 - 100 = 125
The percentage increase would now be :
125/100 * 100 = 125%
