a. \(82.1\ \text{m}^2\ (1\ \text{d.p.})\)

b. \(1023.8\ \text{mm}^2\ (1\ \text{d.p.})\)

Show Worked Solution

a.	\(\text{Area}\)	\(=l\times b\)
		\(=7.2\times 11.4\)
		\(=82.08\)
		\(=82.1\ \text{m}^2\ (1\ \text{d.p.})\)

b.	\(\text{Area}\)	\(=l\times b\)
		\(=67.8\times 15.1\)
		\(=1023.78\)
		\(=1023.8\ \text{mm}^2\ (1\ \text{d.p.})\)
