Question

5. A farmer's field has the dimensions shown. He needs to find the area of the field so that he knows how much seed to buy. 1į km 2 km تازه N 1 square kilometers

Answer 1

The area of the field = area of the shape of the rectangle

As shown in the figure

Length = L = 2 3/4 km

Width = W = 1 1/3 km

Area = A = Length x Width

`A=2(3)/(4)\cdot1(1)/(3)=(4\cdot2+3)/(4)\cdot(3\cdot1+1)/(3)=(11)/(4)\cdot(4)/(3)=(11)/(3)=3(2)/(3)km^2`

so, the answer is area = 3 2/3 square kelometers
