Find the area of the figure. Round to the hundredth place when necessary.

Step-by-step explanation:

We have to cut this figure into several other figures, refer to the attached diagram where I have shown that the given figure can be cut into 3 different figures;

1. Rectangle

2. Triangle

3. Parallelogram

So we are going to find the area of these 3 shapes then we will add them together that will give us the area of whole figure.

Area of Rectangle:

The area of rectangle is given by

Area of Parallelogram:

The area of parallelogram is given by

Area of Triangle:

The area of triangle is given by

Area of whole figure:

Therefore, the area of the whole figure is 155 square yd.

so what is the problem what are they asking you to solve

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
