The perimeter of a rectangular piece of land is 280m. People divide the land into two small pieces: a square, a rectangle. The total perimeter of the two small plots is 390m. Calculate the area of ​​the original piece of land.

Answers

Answer 1
Answer:

Step-by-step explanation:

Length of the Rectangular piece of the land = 12 + 1/2 m = 25/2 m

Breadth of the Rectangular piece of the land = 5 + 1/5 m = 26/5 m

If 4 small square flower bed of side length 1 m are made at center.

To find: Area of the rectangular land , Perimeter of the rectangle and Area of land left when flower bed are mad.

Perimeter of the rectangle = 2 × ( length + breadth )

= 2 × ( 25/2 + 26/5 )

= 2 × ( 177/10 )

= 177/5 m

= 35.4 m

Area of the rectangular land = Length × Breadth

= 25/2 × 26/5

= 5 × 13

= 65 m²

Area of a flower bed = side × side = 1 × 1 = 1 m²

Area of 4 flower bed= 4 × 1 = 4 m²

Area left in the land = 65 - 4 = 61 m²

Therefore, Perimeter of the land is 35.4 m

Area of land is 65 m²

Area of the land left after flower beds is 61 m²

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

The fractions are given in the question following:

1 4/7 × 2/5

To multiply fractions, you multiply the numerators (the top numbers) to get the numerator of the answer and multiply the denominators (the bottom numbers) to get the denominator of the answer.

As per the question, we have

⇒ 1 4/7 × 2/5

Convert mixed numbers to fractions

⇒ 11/7 × 2/5

⇒ (11 × 2)/(7 × 5)

Apply the multiplication operation, and we get

⇒ 22/35

Therefore, the answer is 22/35.

Jesse earns $12.62 an hour, plus she earns overtime for hours exceeding 40 hours per week. What is her gross weekly pay for working 47 hours if she gets time and a half for overtime?A) $541.73
B) $600.14

Answers

the correct answer is c) $637.31

12.62 x 40 = 504.8

time and a half is the amount you get paid + half the amount you get paid 

so half of 12.62 is 6.31 + 12.62 = 18.93

18.93 x 7 = 132.51

504.8 + 132.51 = 637.31

I am in a game show.In this game show there are 3 doors.

Should I open door A or should I open door B?Would my chances of winning a Ferrari increase if I were to open door A instead of door B?Explain your answer and justify why you are correct...
