Task is to construct two brick columns of the dimensions shown on which an iron gate will eventually be hung. Because the bricks
measure 8" long by 3 1/2" wide by 21/2" high, you decide to build each column by laying the bottom row of
bricks as shown.
How much ground area will be covered by the first row of bricks laid (both columns) as shown above?
sq. in.

Step-by-step explanation:
Given that the triangular indentation has an area of 100 in.² and the base and height of this traingle are represented by expressions 3x and x+3 respectively . We need to find out the <u>perimeter </u>to the nearest tenth.
As we know that the area of triangle is ,
Substituting the respective values,
On using the <u>Quadratic</u><u> formula</u> , we have;
On simplifying above , we will get ,
Since sides can't be negative, therefore,
Therefore ,
Next let's find out the <u>hypotenuse </u>using Pythagoras theorem, as ;
Now we may find perimeter as ,
