Question

12. Find the area of a field with length 105 m and breadth 90m. Also, find the
length of fence required to be put around the field. (5)​

Answer 1

Given :- Length = 105 m

Breadth = 90 m

To find :- Area

We know that,

Area = Length × Breadth

= 105 × 90 = 9,450 m²

Length of fence required = Perimeter of the field

Perimeter = 2(Length + Breadth)

= 2(105 + 90)

= 2(195)

= 390 m

Therefore, Area of field = 9,450 m² and Length of fence required = 390 m

Hope it helps!

Answer 2

Length of field = 105m

Breadth of field = 80m

Thus area= 105x 90 m

= 9,450 m
