Answer:
Step-by-step explanation:
base b = 2 in
slant height L = 7 in
lateral area = 4·½bL = 4·½·2·7 = 28 in²
base area = b² = 4 in²
surface area = 28+4 = 32 in²
If b = 14 and L = 49:
lateral area = 4·½·14·49 = 1372 in²
base area = 196 in²,
and surface area = 1372+196 = 1568 in²
The surface area has multiplied by 49.
