GivEn:
- Length of rectangle = x+3
- Breadth of rectangle = x+7
To finD:
- Area of rectangle.
Solution:
We have given that length and breadth of recrangle is x+3 and x+7 respectively.
Formula using:
Area of rectangle = Length× Breadth.
Where:
- Length = x+3 ••••(given)
- Breadth = x+7 ••••( given)
Putting values in formula:
Area of rectangle = Length × Breadth
→ Area of rectangle = (x+3) × (x+7)
→ Area of rectangle = x(x+7) +3(x+7)
→ Area of rectangle = x²+7x+3x+21
→ Area of rectangle = x²+10x +21
