Question

A rectangle has a length of 8ft
and a width of 4 ft. If it.
expands/ increases by 50%. What
is the new area?​

Answer 1

Answer:

48 sq ft

Step-by-step

I am pretty sure they mean what is the new area if the current area is expanded so: 100% + 50% = 150%

4 times 8 = current area = 32 sq ft

32 times 1.5 = new area = 48 sq ft

in the circumstance in which they were talking about the side lengths and not the original then it would be

8 times 1.5 = 12

4 times 1.5 = 6

6 times 12 = area = 72 sq ft
