Faliha runs around a square field of side 70m, while Rameen runs around a rectangular field with length 90m and breadth 60m. Who

$\huge\sf\green{Answer :- }$

<h2>Given :- </h2><h2 />

Side of the square field = 70m

Length of the rectangular field = 90m

Breadth of the rectangular field = 60m

Perimeter of the square field

Perimeter of the rectangular field

<h2>Solution :-</h2>

Perimeter of the square = 4 × side

By substituting values,

⇒ 4 × 70m

➥ 280m

<h3><u>Hence, </u><u>Faliha</u><u> runs 280m around a Square </u><u>field</u></h3>

Perimeter of the rectangle = 2( length + Breadth)

By substituting values,

⇒ 2( 90m + 60m )

⇒ 2( 150m)

➥ 300m

<h3><u>Hence, Rameen runs 300m around a rectangular field</u></h3>

By comparing perimeters, Rameen runs more than Faliha

Distance runs more by rameen = Distance covered by rameen - distance covered by faliha

By substituting values,

⇒ 300m - 280m

➠ 20m

<h3><u>Hence, </u><u>Rameen</u><u> runs more around a rectangular field by 20</u><u>m</u></h3>

What is the result when (2x+2)^2 is subtracted from 1

geniusboy [140]

Answer:

- 4x² - 8x - 3

Step-by-step explanation:

We want to calculate

1 - (2x + 2)² ← expand using FOIL

= 1 - (4x² + 8x + 4) ← distribute parenthesis by - 1

= 1 - 4x² - 8x - 4 ← collect like terms

= - 4x² - 8x - 3

Answer:

75+(-50)=75-50

Step-by-step explanation:

-let x be the profit made last week and y be the profit made this week.

-The two week profit/ loss is given as:

$Profit=x+y$

#We substitute actual values to calculate the profit/loss made:

$Profit=x+y\\\\=75+(-50)\\\\=75-50\\\\=\$25$

Hence, the two-week combined profit is $25.00
