The correct answer is "Keep the base the same and then subtract the exponents." This applies to dividing exponents with the same bases however. If the two terms were multiplying, the answer would be "Keep the base the same and then add the exponents."

$\huge{ \mathfrak{ \underline{ Answer} \: \: ✓ }}$

Radius (r) = 8m

Angle made at centre $(\theta)$ = 140°

$\boxed{ \mathrm{length \: \: of \: \: arc = \dfrac{ \theta}{360 \degree} \times 2\pi r}}$

$\dfrac{140}{360} \times 2 \times 3.14 \times 8$

$\dfrac{7}{18} \times 50.24$

$\dfrac{351.64}{18}$

$19.54 \:m$

Work please and points for this

sergiy2304 [10]

11×12=132
25-11=14
14/2=7, which is the bottom length of the triangles
A triangle plus a similar triangle=a square, so you would do length×height to solve it
7×12=84
84+132=216
The area is 216 ft
