GIVEN THE FIGURES MUST HAVE THE SAME AREA
NOTE THE FIRST SHAPE IS A TRIANGLE WITH
b WHICH IS THE BASE WITH MAGNITUDE 8
AND THE h WHICH IS THE HEIGHT WITH MAGNITUDE (X+4)
WE KNOW THAT THE FORMULA TO CALCULATE THE AREA OF A TRIANGLE IS GIVEN BY
SUBSTITUTE THE GIVEN VALUES IN THE FORMULA EQUATION AND SIMPLIFY TO GET THE EXACT EQUATION THAT REPRESENTS THE AREA OF THE TRIANGLE.
NOW LET US FOCUS ON THE AREA OF A RECTANGLE GIVEN BY FORMULA A=l×b
where l which is the length is given by (x+6) and The breadtg is given by 3
THEREFORE THE AREA OF THE RECTANGLE IS
NOW EQUATE THE AREA OF THE TRIANGLE WITH THE AREA OF THE RECTANGLE TO FIND THE VALUE OF X SUCH THAT THEIR AREAS WILL BE EQUAL
x=2
GOODLUCK!!
