Let's use y

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

inn [45]

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

<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>

Step-by-step explanation:

Slope is found by using

m= (y2-y1)/(x2-x1) hwere the points are (x1,y1) and (x2,y2)

= (-3-3)/(3--5)

= (-6)/(3+5)

= -6/8

PLEASEEEE HELPPPPPP ASAPPPPP

Burka [1]

Answer:

7.07

Step-by-step explanation:

Angle M is 63 degrees because all 3 angles must add to 180.

Now use the law of sines:

sin(90)/x = sin(63)/6.3

Cross multiply: 6.3 sin (90) = x sin (63)

Divide by sides by sin (63): (6.3 sin (90))/sin (63) = x

Use a calculator: 7.07
