To find the area of a rectangular, you have to use the formula → a = base × height
Which is the same thing as your formula!
For the sake of this problem, I’ll use your formula → a = L × w
⓵ Place the information you know in the formula :
a = ?
L = 8cm
W = 6cm
→ a = 8 × 6
→ a = 48cm² → Your answer!
There you go! I really hope this helped, if there’s anything just let me know! ☻
