Answer:

16ft x 16ft

Step-by-step explanation:

Square shaped, so side lengths are all the same size, so 16ft by 16ft. 256 would also need to end in a 5 to be a product of 15 by 15 but would end in six for 16x16 (5*5 and 6*6 will show last digit of the number)

Help? mathhhhhhhhhhhhhhhhhhhhhhhhhhhh

Answer:

a + 20 = 7*12 (multiplied both sides by 12)

a + 20 = 84 (calculated 7*12)

a = 84 - 20 (subtracted 20 on both sides)

a = 64 (calculated 84-20)

Find the area of the figure.

Ivanshal [37]

Step-by-step explanation:

Area of Rectangle at the top =

Length x Width

$= 3.5 \times 3 \\ = 10.5 {mm}^{2}$

Area of Quarter- Circle = 1/4 x Area of Circle

$= \frac{1}{4} \pi {r}^{2} \\ = \frac{1}{4} \pi( {3.5}^{2} ) \\ = 3 \frac{1}{16} \pi {mm}^{2}$

Area of Rectangle at the right = Length x Width

$= 5.5 \times 3.5 \\ = 19.25 {mm}^{2}$

Total Area = Area of 2 Rectangles + Area of Quarter Circle

$= 10.5 + 3 \frac{1}{16} \pi + 19.25 \\ = 29.75 + 3 \frac{1}{16}\pi \\ = 32 \frac{13}{16}\pi {mm}^{2}$

I will leave the answer in terms of pi as I'm not sure if you need to round off your answer.
