God loves you
Have a great day or night :)
16•16=256
A quarter is missing so 256/4=64
64•3=192 is the total square area.
When you find the area of a triangle you usually do (b•h)/2
Since this right here is equal triangles for both ways you can simply divide 192/2=96ft^2
Answer:
it's easy hope I could help
Step-by-step explanation:
the -3 goes on the y line
4/3 goes on the positive side so on the y and x
Answer:
Because it is a rectangle, the area is expressed as A = xy, or length times width.
Because it is next to the river, he only needs to fence three sides, so F = x + 2y.
Knowing the amount of fencing available is 7500m, we get:
7500 = x + 2y solve for x
x = 7500 - 2y substitute into the area equation
A = (7500 - 2y)y distribute
A = -2y2 +7500y
You can see that this is a parabola which opens down, meaning that the point of maximum area will be at the vertex, y = -b/2a = -7500/[2(-2)] = 1875
x = 7500 - 2(1875) = 3750
A = 3750(1875) = 7,031,250 m2
Step-by-step explanation:
the answers are
the bases are congruent,
the volume of the first solid is twice as much as the volume of the second solid,
and
if the dimensions of the second solid are x by x by h, the first solid has 4xh more surface area than the second solid
