<h2>Area of shapes</h2><h3> a) Triangle</h3>base = b = 7 km
altitude or height = h = 3.8 km
length = l = 8.2 cm
width = w = 7 cm
= 8.2 * 7
= 57.4 cm²
<h3>c) Parallelogram</h3>base = b = 9.1 km
height = h = 5 km
= 9.1 * 5
= 45.5 km²
<h3>d) Trapezium</h3>Parallel sides a = 8.9 m & b = 2.7 m
height = h = 4.2 m
