4-72.

Area = (base)(height)

Area = (48)(102)

Area = 4896 sq. units

Area = (base)(height)

Separate the rectangle into two rectangles, then add the two areas to find the total area.

Area = (13· *x*) + (13· 7)

Area = 13*x* + 91

For parts (c) and (d), use the same strategy outlined in part (b).
