Find the area of a rectangular field in acres whose sides are:(1) 200

1.	Find the area of a rectangular field in acres whose sides are:(1) 200 m and 125 m(ii) 75 m 5 dm and 120 m
Answer» (i) Given length of the rectangular field = 200 m Breadth of the rectangular field = 125 m We know that area of the rectangular field = Length x Breadth = 200 m x 125 m = 25000 m² = 250 acres [Since 100 m² = 1 acre] (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 area of the rectangular field = Length x Breadth = 75.5 m x 120 m = 9060 m² = 90.6 acres [Since 100 m² = 1 acre]

Find the area of a rectangular field in acres whose sides are:(1) 200 m and 125 m(ii) 75 m 5 dm and 120 m

Answer»

(i) Given length of the rectangular field = 200 m

Breadth of the rectangular field = 125 m

We know that area of the rectangular field = Length x Breadth

= 200 m x 125 m

= 25000 m²

= 250 acres [Since 100 m² = 1 acre]

(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 area of the rectangular field = Length x Breadth

= 75.5 m x 120 m

= 9060 m²

= 90.6 acres [Since 100 m² = 1 acre]
