What happens to the area of the triangle, when the base of the triangle is increased by 5 times?
Decreases by 5 times
Decreases by 7 times
Increases by 5 times
Increases by 7 times
Explanation:
The area of a triangle is half the product of any base b and the corresponding height h.
New base of the triangle = 5b
[Base is increased by 5 times.]
New area of the triangle =$ \dfrac{1}{2} × 5b × h = 5\left(\dfrac{1}{2}bh\right)$ = 5(original area of the triangle)
The area of the triangle increases by 5 times.
