6.93 should be your correct answer
X^3 + 5^3
(x+5)x(x^2-X x 5+5^2)
(x+5)x(x^2 -5x+5^2)
(x+5)x(x^2 -5x+25)
(x+5) x (x^2 -5x+25)
Cost of fence for a meter = 6.88
For 32.5 m, it would be = 6.88 * 32.5 = 223.6
D)223.60 is answer
Area= angle theta/360 *pi*r*r
=60/360* pi* 12*12
=24pi
Answer:
The breadth is about 6.32cm and the perimeter is about 50.56cm.
Step-by-step explanation:
The formula for the area of a rectangle is l * w = A, where l is the length, w is the width or breadth, and a is the area. If the length is 3 times the width, it can be written as 3w. This can be substituted into the formula along with the area to get 3w * w = 120, or 3w^2 = 120. Then it could be solved as an equation.
(3w^2)/3 = 120 / 3
w^2 = 40
w ~ 6.32
Then 6.32 can be multiplied by 3 to find the length, whch is 18.96. The formula for the perimeter of a rectangle is 2(l + w) = P.
2(6.32 + 18.96) = P
2(25.28) = P
50.56 = P
