Find the area of rectangle if the length and breadth are (2x +3) cm and (4x+5y) cm respectively.
Answers
Solution!!
The length and breadth of a rectangle are given in the question. We have to find the area of the rectangle. We will use the area formula to find the area.
Length = (2x + 3) cm
Breadth = (4x + 5y) cm
Now, let's apply the formula and substitute the values given.
Area = Length × Breadth
Area = (2x + 3) × (4x + 5y)
Area = 2x(4x + 5y) + 3(4x + 5y)
Area = (8x² + 10xy + 12x + 15y) cm²
Hence, the area of the rectangle is (8x² + 10xy + 12x + 15y) cm²
Things to remember:-
→ Area is always in square units.
→ Before using the formula, make sure the units are same.
→ The calculation in the end is to be done carefully otherwise your answer maybe wrong and you can lose marks.
