How can the area of this triangle be determined by forming a rectangle? Select from the drop-down menus to correctly complete th
Nuetrik [128]

The area of the triangle can be found by copying the triangle and putting the bases together such that it forms the diagonals of the triangle.

<h3>What is the area of the triangle?</h3>

The area of the triangle is half the product of the height of the triangle and the base of the triangle.

As we know that the area of a rectangle is double the area of a triangle,

therefore, in order to calculate the area of a triangle we need to convert it to a rectangle and then divide the area of the rectangle by 2.

Also, we know that the diagonal of a rectangle divides it into two equal triangles, therefore, we will put the triangle along the diagonal of the base.

Thus, to find the area of the triangle we will copy the triangle and put the base of the together such that it forms the diagonals of the triangle.

Since the triangles are put on each other along the base, therefore, the height(h) of the triangle will be the length of the rectangle, and the breadth of the triangle will be equal to the base of the triangle(b).

Solve the following system<br> 6x-3y=15<br> x+3y=-8
pentagon [3]
<h2>Answer:</h2>

This system can be solved for x by elimination.

6x - 3y = 15\\  x + 3y = -8\\\\7x = 7\\\\x = 1

Now, with what we found for x, we plug it back into one of the equations to solve for y. I chose the second one.

1 + 3y = -8\\\\3y = -9\\\\y = -3

Now, we have our solution.

(1, -3)
