Answer: A.56 sq. units
Step-by-step explanation:
A=( a+b)h/2
(12+16)4/2
(28)2
56
A=56
The area of a square or a rectangle (which is the shape of any room in a house) is:
Area = width x length
So, in this case:
Area = 51 m x 26 m = 1326 Sq meters. Which is pretty big if you ask me.
Anyhow, Ms Melcher needs to buy 1326 sq meters
Add 6 to both sides
2m2+7m+6=0
