To calculate the percentage increase:
First: Find out the difference (increase) between the two numbers you are comparing.
It is computed by: Increase = New Number - Original Number
Second: Divide the increase by the original number and multiply the answer by 100.
It is computed by: % increase = Increase ÷ Original Number × 100.
So in the problem:
First step:Increase = 1000 – 100
Increase = 900
Second:
% increase = 900 / 100 x 100%
increase = 900% increase

Answer:
perimeter: 90z+176
Explanation:
perimeter = measure of all length sides
perimeter for this shape:
45z + 40 + 15z + 48 + 20z + 60 + 10z + 28
group terms like this ↓
45z+15z+20z+10z+40+48+60+28
addition of terms ↓
45z+15z+20z+10z+176
this is how final result would look ↓
90z+176

Answer:
Step-by-step explanation:
Let w be the width
Length = 3w +15
Perimeter = 94 cm
2*(length + width) = 94
2*(3w+15 + w) = 94
2*( 4w + 15) = 94
4w + 15 = 94/2
4w +15 = 47
4w = 47 -15
4w = 32
w = 32/4
w = 8 cm
Length = 3w +15 = 3*8 + 15 = 24 +15 = 39
Length = 39cm
Area = length * width = 39*8 = 312
Area = 312 cm²
