Answer:
600 ft³
Step-by-step explanation:
Base area: B
Base is triangle
base = 12 ft and height = 5 ft
Area of triangle = B = 

H = 20 ft
Volume = B * H
= 30 * 20
= 600 ft³
Answer:
N12.8
Assume the money in the box Is M.
therefore, 3/4 of M=N4.80.
Recall N1=100k..... where k 'kobo'
N4.80=X
X=4.80x100. this gives us 480k.
this implies that 3/4 X M= 480k
therefore by cross multiplication, and dividing by 3; 3M=480 X 4
M = (480 X 4) ÷3
M=1280k
converting from kobo' to Naira. the rate of conversion is;
100k = N1
1280k=?
M in naira= 1280/100
M is N12.8
Using the Pythagorean theorem:
Length of wire = sqrt(34^2 + 8^2)
Length of wire = sqrt(1156 +64)
Length of wire = sqrt(1220)
Length of wire = 34.9285 feet
There are 2 wires:
34.9285 x 2 = 69.857 feet
Round off as needed.
Answer:
Hi,
Step-by-step explanation:
The playground 's area is the difference of 2 squares:
20²-10²=(20+10)*(20-10)=30*10=300 (ft²)
First we will find the total measure of the second base.
Second base is extended more so that meas it will measure extended part plus the first base.
Second base = 7 + 5 = 12.
Now for the area.
A = 1/2(b1+b2)(h)
A = 1/2(7 + 12)(7)
A = 66.5
The area is 66.5 ft²
Hope this helps :)
