Question
Find the area $ A $ of a rectangle if side $a = \sqrt{ 98 }\, \text{cm}$ and side $b = \sqrt{ 8 }\, \text{cm}$.
Answer
$28\, \text{cm}^2$
Explanation
To find area $ A $ use formula:
$$ A = a \cdot b $$After substituting $a = \sqrt{ 98 }\, \text{cm}$ and $b = \sqrt{ 8 }\, \text{cm}$ we have:
$$ A = \sqrt{ 98 }\, \text{cm} \cdot \sqrt{ 8 }\, \text{cm} $$$$ A = \sqrt{ 98 }\, \text{cm} \cdot \sqrt{ 8 }\, \text{cm} $$$$ A = 28\, \text{cm}^2 $$This page was created using
