Answer:

Step-by-step explanation:
Original dimensions of the rectangle


Area of the rectangle

Scale factor = 1.1
New dimensions


The new area of the rectangle

Percentage change is given by

The percentage by which the area of the rectangle increases is
.
Answer:
47 %
Step-by-step explanation:
from 1.50 to 2.20 there's a 46.67 increase. to the nearest whole number that's 47%
percent increase formula
% increase = 100 x (final - initial) / absolute value of initial
K=2
- A'=2(2.5)=(4,10)
- B'=2(1,2)=(2,4)
- C'=2(3,1)=(6,2)
Translation of 2 units left means change in x
- A''=(4-2,10)=(2,10)
- B"=(2-2,4)=(0,4)
- C"=(6-2,2)=(4,2)
Translation of 1 units up means change in y
- A'''=(2,10+1)=(2,11)
- B'''=(0,4+1)=(0,5)
- C'''=(4,2+1)=(4,3)
Ok so to find the sum of interior angles the formula is
s=180(n-2)
s is sum and n is the number of sides
so this is a quadrilateral cause it has 4 sides
because of that n=4
substitute
s=180(4-2)
now you can either distribute or do pemdas but its easier and more efficient to just do pemdas
s=180(2)
s=360 degrees
Answer:
15.71m
Step-by-step explanation:
circumference of a circle = 2πr
where r = 2.5m
where π = 3.142
we have,
2*3.142*2.5 = 15.71m
therefore the circumference of a circle with a radius 2.5m = 15.71 m
