7cm
#1 40 m²
#2 32 in²
#3 45 in²
#4 20 mm²
#5 56 cm²
#6 48 in²
#7 84 in²
#8 22 mm²
#9 49 in²
#10 12 ft²

Explanation:

Step1: Recall rectangle area formula

Area = $\text{length} \times \text{width}$

Step2: Substitute given values

Area = $11\ \text{cm} \times 7\ \text{cm}$

Step3: Calculate the product

Area = $77\ \text{cm}^2$

Answer:

$77\ \text{cm}^2$
