Question

Find the area of a rectangular field in hectare whose sides are:
(i) 120 m and 105 m
(ii) 70 m 9 dm and 125 m​

Answer 1

Answer:

(i) Given length of the rectangular field = 125 m Breadth of the rectangular field = 400 m We know that the area of the rectangular field = Length x Breadth = 125 m x 400 m = 50000 m2 = 5 hectares [Since 10000 m2 = 1 hectare] (ii) Given length of the rectangular field =75 m 5 dm = (75 + 0.5) m = 75.5 m [Since 1 dm = 10 cm = 0.1 m] Breadth of the rectangular field = 120 m We know that the area of the rectangular field = Length x Breadth = 75.5 m x 120 m = 9060 m2 = 0.906 hectares [Since 10000 m2 = 1 hectare]Read more on Sarthaks.com - https://www.sarthaks.com/690253/find-the-area-of-rectangular-field-in-hectares-whose-sides-are-i-125-m-and-400-ii-75-dm-and-120
