a rectangular playground is 40 meters by 10 meters. its area will be covered with shredded tires. each bag of shredded tires covers 200 square meters and costs $30. find the total cost for this project.

Answers

First, we need to find the area of the rectangular playground.
To do this, we must multiply 40 by 10.
We get 400 meters².
Now divide 400 by 200 and you get 2.
That means 2 bags will be needed to cover the entire area of the playground.
To find the price, multiply 30 by 2.
The total cost for this project will be $60.
Hope this helped you out! :)

Find the area of the trapezoid by decomposing it into other shapes plzz help i will give brainy board to who every

Answers

The area of the trapezoid is 35 cm².

Solution:

The figure is splitted into two shapes.

The reference image is attached below.

One shape is rectangle and the other is triangle.

Length of the rectangle = 6 cm

Width of the rectangle = 5 cm

Area of the rectangle = length × width

= 6 × 5

= 30 cm²

Base of the triangle = 8 cm - 6 cm = 2 cm

Height of the triangle = 5 cm

Area of the triangle = $(1)/(2) bh$

$$=(1)/(2) *2 *5$

= 5 cm²

Area of the trapezoid = Area of the rectangle + Area of the triangle

= 30 cm² + 5 cm²

= 35 cm²

The area of the trapezoid is 35 cm².
