The difference between the length and the breadth of a rectangle is 16 cm. If its perimeter is 188 cm, then what is its area?
2375 cm2
2145 cm2
2100 cm2
2050 cm2
- We are given that the difference between the length and the breadth of the rectangle is 16 cm.
- The formula for the perimeter of a rectangle is:
$$ \text{Perimeter} = 2(\text{Length} + \text{Breadth}) $$
- Given the perimeter is 188 cm, we setup the equation:
$$ 2(L + B) = 188 \Rightarrow L + B = 94 $$
- We also have:
$$ L - B = 16 $$
- Solving these equations simultaneously:
$$ L + B = 94 $$
Adding these:
$$ 2L = 110 \Rightarrow L = 55 $$
Substituting in \( L + B = 94 \):
$$ 55 + B = 94 \Rightarrow B = 39 $$
- Now, calculating the area:
$$ \text{Area} = L \times B = 55 \times 39 = 2145 \, \text{cm}^2 $$
- Hence, the correct option is: Option 2, 2145 cm²
