Answer 1

Answer:

area of rectangular land=100ft×50ft=5000ft

area of semi circle=1/2πr²=1/2×22/7×25²

=11/7×25×25=982.1ft

area of triangle=1/2(b×h)

=1/2×70ft×50ft

=3500/2=1750ft

total surface area of Land=1750+982.1+5000

=6750+982.1

=7732.1ft

Answer 2

Answer:

Step-by-step explanation:

Area of rectangle = lb = 100x50 = 5000 ft^2

Area of triangle = 1/2bh = 70x25 = 1750 ft^2

Area of Semi-circle = 1/2*πr^2

                                =1/2*3.14*25*25

                                =1.57*625

                                = 981.25 ft^2

Thus, total area = 5000 + 1750 + 981.25

                          = 6750 + 981.25

                         = 7731.25 ft^2//
