Question

A TRIANGULAR FIELD HAS DIMENSIONS 24M, 7M AND 25M. IT HAS A ROAD AROUND IT WHICH IS 1M WIDE. FIND THE AREA OF THE ROAD. (Hint-Use Heron’s formula)

Answer 1

Answer:

32.79m²

Step-by-step explanation:

Area of bigger triangle:

s = (26 + 9 + 27)/2 = 62/2 = 31

Area = √31×5×22×4 = √13640 = 116.79

Area of field:

s = (24+7+25)/2 = 56/2 = 28

Area = √28×4×21×3 = 84

Area of road = 116.79 - 84 = 32.79m²
