Question

The area of a rectangular field is 1600 sq.m. If the length of the field is 80m, find the breadth and perimeter of the field.

Answer 1

Answer:

Perimeter of rectangle is 200m

Breadth of rectangle is 20m

Step-by-step explanation:

Given:-

• Area of rectangular field=1600m²

• Length of field=80m

To find:-

• Perimeter of rectangular field

• Breadth of field

Solution:-

We can find breadth of rectangular field by applying formula for area of field:

Area of rectangle=Length×Breadth

Now put values of area and length

1600m²=80m×Breadth

1600m²/80m=Breadth

20m=Breadth

So the required breadth is 20m

Now apply formula for perimeter of rectangle:

Perimeter of rectangle=2(L+B)

Here, L refers to length and B refers to breadth

Perimeter of rectangle=2(80m+20m)

Perimeter of rectangle=2(100m)

Perimeter of rectangle=200m

So the required perimeter of rectangle=200m
