Answer:
Step-by-step explanation: L= length w= width p= perimeter
L=3W p=55CM
P. of rectangle= 2(l+w)=55cm
L+w= 55/2= 27.5 cm
3w+w=27.5cm
4w=27.5cm
w=27.5/4=6.875cm w=6.875cm L= 3w=6.875*3=20.625cm
Answer:
Step-by-step explanation:
Given
Area of Sector : Area of Circle = 3 : 5
Required
Determine the central angle
The question implies that
Multiply both sides by 5
Multiply both sides by Area{circle}
Substitute the areas of sector and circle with their respective formulas;
So, we have
Divide both sides by 
Multiply both sides by 360
Divide both sides by 5
Hence, the central angle is 216 degrees
The answer is 3 inches wide and 5 inches tall and 2 inches wide and 5 inches tall. The second from the top.
I hope this helps.
Answer:
78
Step-by-step explanation:
Find the prime factorizations of the two numbers:
26 = 2 * 13
39 = 3 * 13
The LCM is the product of common and not common factors with the higher exponent.
LCM = 2 * 3 * 13 = 78
Answer: 78
Answer:
875cm^2
Step-by-step explanation:
since opposite sides are equal
3x-y=2x+y
x=2y
y=x/2 ....(i)
thus new length=2x+y
=2x+(x/2) [using (i)]
=(4x+x)/2
l=5x/2 .....(ii)
now,
perimeter=2(l+b)=120cm
l+b=60cm
from figure and using (ii)
[5x/2]+2x-3=60
[5x+4x-6]/2=60
9x-6=120
9x=126
x=126/9
x=14 ..........(iii)
substitute (iii) in (i)
y=14/2
y=7 ...........(iv)
From figure,
length=2x+y [using (iii) and (iv)]
=2x14+7
length=35cm
breadth=2x-3
=2x14-3 ....[using(iii)]
=28-3
breadth=25cm
now,
Area=lxb
=35x25
=875cm^2
