Question

Find the cost of farming of an rectangular wooden board of sides 20m and 24m at the rate of $31 per meter..​

Answer 1

area of rectangle is equal to length into breath

20m*24m

= 480m2

cost of 31 per metre

1. =31*480

• =14880

Answer 2

Answer:

$2788

Step-by-step explanation:

Given,

Length of Board = 24m

Width of Board = 20m

Thus the parameter of the board = 2(Length + Width)

                                                       = 2(24 + 20)

                                                       = 2 × 44

                                                       = 88 m

Given that rate of farming is $31 per meter

Thus total farming with this rate = 88 × $31

                                                     = $2788

The parameter of a rectangular shape = 2(Length + Width)

The area of a rectangular shape = Length × Width

A rectangle(it has four sides) is a shape whose opposite sides are parallel and equal in length. Each of the side makes an angle of 90° with its corresponding touching side.
