Question

If the height of a triangle is doubled. Find the percentage change in the area of the triangle.

Answer 1

Answer:

100%

Step-by-step explanation:

let the area of a triangle be 1/2 bh.

now, height is doubled,

therefore, new area = 1/2 b2h

= bh

so, percentage of increase in area

= ((1/2bh)/bh *100)% - 100%

= 200% - 100%

= 100% ans.
