Q121 of 131 Page 226

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?


Let the increase in length be x m.


Give, increase in area of the field = 650 m2


Area of expanded wheat field – Area of original wheat field= 650 m2


(32 + x ) × 26 – 32 × 26 = 650


26 (32 + x – 32) = 650


x = = 25 m


Length of expanded wheat field = 32 + x = 32 + 25 = 57 m
