Answer:

Area = 23.12 cm²

perimeter = 24.28 cm

Step-by-step explanation:

top shaded region is circular arc with 90° sector angle

so perimeter of arc is 90 / 360 * 2πr

here radius of arc is half the length of square side

r = 6.8/2 = 3.4

top area shaded perimeter = 90/360 * 2 * 3.14 * 3.4

= 1/4 * 2 * 3.14 * 3.4

= 5.338

bottom region perimeter is also same

total perimeter of shaded region is = side + side + two arcs

= 6.8 + 6.8 + 2 * 5.338

= 13.6 + 10.676

= 24.276

= 24.28

Area of top shaded region is 90/360 * πr²

A = 1/4 * 3.14 * 3.4²

= 9.0746

bottom shaded region area is half of area of square - area of bottom arc

= 6.8 * 3.4  - 9.0746

= 23.12 - 9.0746

= 14.0454

so total area of shaded region is 9.0746 + 14.0454

= 23.12

or you can just calculate area as half of area of total square = 6.8² / 2

= 23.12

Workers need to know the area of a park to determine how much grass seed to order. A worker drew a sketch of the park to find it
Aneli [31]

The area of the park is 1640 square meters.

<h3>What is a quadrilateral?</h3>

A quadrilateral is a plane shape with four sides and four angles.

The above figure is made up of two quadrilateral; a square and a trapezium.

Analysis:

Area of park = area of square + area of trapezium

Area of park = 1/2(a + b)h + s x s

where a = length of smaller parallel side of the trapezium = 40m

           b = length of the larger parallel side = 48m

           h = height of trapezium = 35m

           s = length of side of square = 10m

Area of park = 1/2(40 + 48)x35 + 10 x 10 = 1640 square meters

In conclusion, the area of the park is 1640 square meters

The table shows pattern p and patterns q complete the table
mario62 [17]

ANSWER

P=8,Q=16

EXPLANATION

We can see from the table that both pattern P and Q have an initial value of 24.

Pattern P is reducing by a constant difference of 4.

The next value for pattern P is

12-4=8.

Also pattern Q is reducing by a constant value of 2.

The next value for pattern Q is,

18-2=16
