Answer:

a) the new perimeter is 2 times the old perimeter

b) the new area is 4 times the old area

Step-by-step explanation:

b) the doubling of the length and width affects the area formula like this:

old triangle area formula = 1/2bh

new triangle area formula = 1/2(2b)(2h),   you see the 2 x 2 causes the area to be 4 fold
