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