19. Perimeter of rectangle = 2(l + b)

l = 25m

b = 16m

Perimeter of rectangular park = 2 (25 + 16)

= 50 + 32

= 82m

Perimeter of square park = 82m

(given that, perimeter of rectangular and square park are equal)

Perimeter of square = 4a

4a = 82

a = 82/4

a = 20.5m

Area of square park = a²

= 20.5²

= 420.25m²

20. Perimeter of regular hexagon = 6a

a = 2.5

6a = 6 × 2.5

= 15cm

21. Perimeter of regular decagon = 10a

a = 8

10a = 10 × 8

= 80cm

1. Sam walks 3/8 km to school. After school, he walks another (x+1)/3 km to get to work. What simplified rational expression des
Brilliant_brown [7]

Answer:

The answer to your question is (17 + 8x)/24

Step-by-step explanation:

Data

First distance = 3/8 km

second distance = (x + 1)/3 km

Process

1.- Sum both distances

                    3/8 + (x + 1)/3

- Find the Least common factor

                    8   3   2

                    4   3   2

                    2   3   2

                     1   3   3

                          1

LCF = 2x 2 x 2 x 3 = 24

- Sum the fractions

                  3/8 + (x + 1)/3 = (9 + 8(x + 1)) / 24

-Simplification                                          

                                         = (9 + 8x + 8) / 24

-Result

                                         = (17 + 8x)/24

The length of a rectangle is 5 cm more than its width. The perimeter is 82 cm. Find the length of the rectangle.
weeeeeb [17]

We will represent the length of the rectangle as l and the width as w.


From this problem, we can say l = w + 5. We can also deduct an equation from the second sentence:

2l + 2w = 82

2(w + 5) + 2w = 82 (from substitution)

2w + 10 + 2w = 82

4w = 72

\boxed{w = 18}


Using this value for w, we can find l:

l = 18 + 5

\boxed{l = 23}


The length of the rectangle is 23 cm and the width of the rectangle is 18 cm.

Solve the triangle give the measure of angle G
zalisa [80]

Answer:

G = 46 degrees

Step-by-step explanation:

Here, we want to find the measure of angle G

Mathematically, as we can see, what we have is a right triangle

For a right triangle , the sum of angles is 90 degrees

Thus, if we add the two internal angles, we get 90 degrees

Hence;

44 + G = 90

G = 90-44

G = 46 degrees
