#15
calculate the area:
9ft
5ft
#1 40 m² #
#2 32 in² #
#3 45 in² #
#4 20 mm² #1
#5 56 cm² #15
#6 48 in² #16
#7 84 in² #17
#8 22 mm² #18
#9 49 in² #19
#10 12 ft² #20

Explanation:

Step1: Recall rectangle area formula

Area = length $\times$ width

Step2: Substitute given values

Length = $9$ ft, Width = $5$ ft
$\text{Area} = 9 \times 5$

Step3: Calculate the product

$\text{Area} = 45$

Answer:

$45$ ft$^2$
