Answer 2

Given :-

• The perimeter of rectangular field is 240m.

• The length of rectangular field is 90m.

To Find :-

• The breadth of rectangular field.

• The area of rectangular field.

Solution :-

According to the question,

The perimeter of rectangular field is 240m.

Perimeter of rectangle = 2 ( l + b ) ....(1)

We have,

• p = 240 m

• l = 90 m

putting in equation 1.

➝ 240 = 2 ( 90 + b )

➝ 240 = 180 + 2b

➝ 240 - 180 = 2b

➝ 2b = 60

➝ b = 30 m

Hence, The breadth of rectangular field is 30 m.

Area of rectangle = l × b

• l = 90 m

• b = 30 m

= l × b

➝ 90 × 30

➝ 2700 m²

Hence, The area of rectangular field is 2700 m².
