Answer:
Length = 502 ft
Width = 212 ft
Step-by-step explanation:
Recall the formula for the perimeter of a rectangle of length "L" and width "W":
Perimeter = 2 L + 2 W = 1428 ft
Now, since the length is 78 ft more than twice the width, then we can write this in mathematical form as:
L = 2 W +78
so, 2 W = L -7 8
and now replace "2 W" with it equivalent "L - 78" in the first perimeter equation and solve for "L":
2 L + L - 78 = 1428
3 L = 1428 + 78
3 L = 1506
L = 1506/3
L = 502 ft
Then the width W can be obtained via:
2 W = L - 78
2 w = 502 -78
2 W = 424
w = 212 ft
We are given the equation we just have to plug in the numbers
8 + 2 * 3 + 3 * 4
8 + 6 + 12

Your answer is 26 trees
You have the area of the squares
100 in^2
area of a square = l*w
so length and width of the square both equal 10in
there are 4 squares going across the semi circle so...
diameter of semicircle is 10+10+10+10 =40in and radius is 20in
to find area of semicircle the formula is 1/2 pi r^2
so plug in the numbers 1/2(3.14) (20)^2 = 628 in ^2
now add that to area of big square part of window
40 inches length * 40 inches width = 1600in^2 (or you can just add them all up )
add up the areas now 1600+628= 2228 in^2
i think that is right
I think it’s 5 I’m not really sure
