Question

If the base and altitude of a triangle are doubled,what will happen to its area

Answer 1

Anarea will be increased by a factor of 4 if the sides are doubled

Step-by-step explanation:

let A1 be the area A1=(1/2)b*h

b=2b;h=2h; then

A2=(1/2)(2b)(2h)=4*(1/2)b*h=4*A1

Answer 2

Step-by-step explanation:

The area of a triangle is given by (1/2)*base*height. If the length of the sides becomes double so does the height. As base and height are becoming double the new area is 4 times the original area. When the length of the sides of a triangle double, the area becomes quadruple.
