Question

If the base was doubled and the height was tripled, how would the area be affected?

Answer 1

step 1

Find the original area

Area of triangle

A=(1/2)(12)(5)

A=30 unit2

step 2

Find the new area

b=2*12=24 units

h=3*5=15 units

A=(1/2)(24)(15)

A=180 unit2

step 3

Divide the areas

180/30=6

that means

the new area is 6 times the original area
