Respuesta :
6 inches more than 2 times the height, 54 square inches the base and height is
b=13.8 inches
h=3.9 inches
Let base and height be b and h respectively,
So ,
b=2h+6
Area = b*h= 54 square inches
So,
(2h+6)(h)=54
2h²+6h=54
h²+3h=27
h²+3h-27=0
h= [tex]\frac{-3 +\sqrt{3^{2}-4(-27)(1) } \\}{2}[/tex]
h=[tex]\frac{-3 +\sqrt{9+108} \\}{2}[/tex]
h=[tex]\frac{-3 +\sqrt{117} \\}{2}[/tex]
h=[tex]\frac{-3 +10.8\\}{2}[/tex]
h=3.9 inches
b=2h+6=13.8 inches
The measurement that indicates the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
The quantity of unit squares necessary to completely cover a shape is its area. As a result, it is stated and measured in square units.
Area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies. Consider your square as being composed of smaller unit squares.
