If given the circumference you can solve for the radius which will be the height of the parallelogram. also with the circumference you can divide by 2 to find the base of the parallelogram. so all you have to do now is times the radius by half the circumference to find the area

3. The perimeter of a rectangular playing field is 504 yards. The area of the

Len [333]

The perimeter is twice the sum of the length and the width:

$P = 2(w+l)$

The area is the product of the dimensions:

$A = wl$

So, the system is

$\begin{cases}w+l=504\\w\cdot l=14276\end{cases}$

Answer:

Step-by-step explanation:

$17. (a^{m})^{n}=a^{m*n}\\\\a^{m}*a^{n}=a^{m+n}\\\\-3k^{2}*(4k^{5})^{3}=-3k^{2}*4^{3}*k^{5*3}\\\\ = -3k^{2}*64*k^{15}\\\\= (-3)*64*k^{2+15}\\\\= - 192k^{17}$

$19. \dfrac{a^{m}}{a^{n}}=a^{m-n}\\\\\\\dfrac{(-7p^{4})*(-8p^{5})}{2p^{3}}= \dfrac{(-7)*(-8)*p^{4}*p^{5}}{2p^{3}}\\\\\\=(-7)*(-4)*p^{4+5-3} \\\\= 28p^{6}\\$

$20)\dfrac{15a^{16}b^{11}}{(3a^{4}b^{2})^{3}}=\dfrac{15a^{16}b^{11}}{3^{3}*a^{4*3}*b^{2*3}}\\\\\\=\dfrac{15a^{16}b^{11}}{27*a^{12}*b^{6}}\\\\=\dfrac{5*a^{16-12}*b^{11-6}}{9}\\\\\\=\dfrac{5a^{4}b^{5}}{9}$

Calculate the surface area of the prism. Measurements are in centimetres

Nata [24]

Answer:

2804 cm²

Step-by-step explanation:

<u>Total area comprises of 6 faces: 2 trapezoids and 4 rectangles</u>

Trapezoid = 1/2*(14+32)*24 = 552 cm² each
Bottom = 17*32 = 544 cm²
Top = 14*17 = 238 cm²
Right side = 17*24 = 408 cm²
Left side = 17*√((24² + (32-14)²) = 17* √900 = 17*30 = 510 cm²

<u>Total area:</u>

552*2 + 544 + 238 + 408 + 510 = 2804 cm²
