Question

#6iFind the area of the triangle by forming a parallelogram.Area =units

Answer 1

Form a rectangle, which is a parallelogram, using the triangle as shown below

Thus, the area of the rectangle is

$A_{rectangle}=l*w=7*5=35$

On the other hand, the area of the triangle is half of that of the rectangle; then,

$A_{triangle}=\frac{1}{2}A_{rectangle}=\frac{35}{2}=17.5$

The answer is 17.5 square units.
