Give possible expresseniory for the length and breadth of a rectangue having A = 35y2 + 13y - 12(Area)

Answer»

ANSWER:

there are TWO NUMBERS of expressible lengths

Step-by-step explanation:

we have A =35y2+13y-12

A=35y2+28y-15y-12

A=(35y2+28y)-(15y+12)

A=7y(5y+4)-3(5y+4)

A=(7y+3)(5y+4)

Find the area of triangle by heron's formula whose sides are 18,34and30

Answer»

Answer:

Area = 269.46

Step-by-step explanation:

In Herons formula we have AREA = $\sqrt{S(S-A)(S-B)(S-<klux>C</klux>)}$

Where A , B , C are Side of traingle

and S = ( A + B + C ) / 2

First we will FIND the value of S

so S = ( 18 + 34 + 30 ) / 24

= 41

now PUT the values of S ,A ,B and C we have

Area of Traingle = $\sqrt{S(S-A)(S-B)(S-C)}$

= $\sqrt{41(41-18)(41-34)(41-30)}$

calculating we will get area = $\sqrt{72611}$

= 269.46
