Answer:
Jyoti?s diagram Area of the park \[=2\times \,\left[ \frac{(15+30)}{2}\times \frac{15}{2} \right]\] \[=\frac{675}{2}\] \[=337.5\,{{m}^{2}}\] Kavita's diagram Area of the park \[=15\times 15\,{{m}^{2}}\,+\frac{15\times (30-15)}{2}\,{{m}^{2}}\] \[=225\,{{m}^{2}}+\frac{225}{2}{{m}^{2}}\] \[=225\,{{m}^{2}}+\,112.5\,{{m}^{2}}\] \[=337.5\,{{m}^{2}}\] Another way of finding the area Area of the park \[=\frac{15\times (30-15)}{2}\,{{m}^{2}}+2\times \left[ \frac{15\times 15}{2} \right]\,{{m}^{2}}\] \[=\,337.\,5\,{{m}^{2}}\].
