Ramesh grew wheat in a rectangular field that measured 32 metres long and 26 metres wide. This year he increased the area for wheat by increasing the length but not the width. He increased the area of the wheat field by 650 square metres. What is the length of the expanded wheat field?
Solution:
Ramesh grew wheat in a rectangular field.
Given, the field measures 32 m long and 26 m wide.
This year he increased the area for wheat by increasing the length but not the width.
He increased the area of the wheat field by 650 m² .
We have to find the expanded length of the wheat field.
Area of rectangle = length × width
Considering initial rectangular field,
Length = 32 m
Width = 26 m
Area = 32 × 26
= 832 m²
Given, increase in area after expanding the length = 650 m²
Increase in area = area of field after expanding the length - area of initial rectangular field
650 = expanded length × 26 - 832
650 + 832 = expanded length × 26
1482 = expanded length × 26
Expanded length = 1482/26
= 741/13
= 57 m
Therefore, the expanded length is 57 m.
