Question

the perimeter of a rectangular field is 500m. amd its lenghth is 150m. find its area​

Answer 1

Step-by-step explanation:

Given that,

The perimeter of a field is 500m. And it's length is 150m.

Step 1 : Find the breadth of the field :

The field is rectangle-shaped

We know that,

Perimeter of a rectangle = 2(l + b)

Where,

• l is length
• b is breadth
• And perimeter is 500m (given)

So,

→ 500 = 2(150 + b)

→ 500 = 300 + 2b

→ 500 - 300 = 2b

→ 200 = 2b

→ 200 ÷ 2 = b

→ 100 = b

∴ breadth of the field is 100m.

Step 2 : Find the area of the field :

Area of the field is given by : length × breadth

→ 150 × 100

→ 15,000m²

∴ Area of the field is 15,000m²✔

Answer 2

Answer:

Perimeter = 2 (L + B)

500 m = 2 (150 m + B)

500 m = 300 m + 2B

500 m - 300 m = 2B

200 m = 2B

200 m / 2 = B

100 m = B

Area of a rectangle = L × B

150 m × 100 m = 15000 m^2
