Answer:
Solution given:
length = (3x+5)
breadth = (2y+4)
we have
area of rectangle: length* breadth
=(3x+5)(2y+4)
opening bracket
=3x(2y+4)+5(2y+4)
=6xy+12x+10y+20
=<u>12x+10y+6xy+20</u><u>u</u><u>n</u><u>i</u><u>t</u><u> </u><u>square</u>
I rounded each number to the nearest whole number and added those.
29 + 79 + 42 = 150
If you add the original numbers you would get 149.5, which rounds to 150.
