Question 1189947


A Land developer is dividing property into sections to make a new neighborhood.

1. Find area the, in square blocks, of the mall section of the property.

 the mall section :

shape of triangle:

{{{A[3]=(1/2)3blocks*3blocks=4.5blocks^2}}}


2.Find the area, in square blocks, of the park section of the property.

trapezoid:

{{{A[3]=((a+b)/2)*h=((8blocks+5blocks)/2)*3blocks=(13*3)blocks^2/2=19.5blocks^2}}}


3.Find the total area, in square blocks, of the sections with homes

rectangles:

{{{A[1]=10blocks*(7+3)blocks=100blocks^2}}}

{{{A[2]=10blocks*8blocks=80blocks^2}}}


total area of the sections with homes:{{{ A=180blocks^2}}}


4.If the developer paid ${{{500.00}}} per square block, how much did she pay for all the property being developed?


find total area of  all the property:

{{{A[p]=4.5blocks^2+19.5blocks^2+180blocks^2=204blocks^2}}}

If the developer paid ${{{500.00}}} per square block, than total cost will be

${{{500.00*204=102000}}}
