Perimiter=2L+2W
w=x
P=80
80=2L+2x
diviide by 2
40=L+x
40-L=x
40-x=L
the area is found by legnth times width
LW or Lx
for a maximum area, try to get the legnths of the sides the same
therefor
L=W=x for max area
40=x+x
40=2x
divide 2
20=x
max area =legnth times width=20^2=400
note: all squares are rectangles, but not all rectangles are squares
L=40-x
A=(40-x)(x)
max area=400 cm^2
Answer:
$12,060
Step-by-step explanation:
LET selling price be rep by x
since he made a profit of 12%, we then add to 100%
100% + 12% = 112%.
to find the selling price, we multiply cost price by 112%
112% x $10768 =
112 / 100 x $10,768
= 1.12 x $10,768 = 12,060
selling price = $12,060.
The equation is 20(3) + 25(4) - 10 = $150, the 3 was given for lawns and the 4 was given for Gardens. Plug and Chug
Hello!

- Diameter of the circle = 12 cm

Area of the Circle

A=πr²
Hey! We have the diameter, not the radius.
Don't panic. In order to find the radius, we should divide the diameter by 2.
So, the radius is 6.
Plug it into the formula:
A=π(6)²
A=π(36)
A≈113 cm
Hope it helps!
Good luck and enjoy your day!
