Answer 1

Answer:

Hello There!

Perimeter of the rectangular field is 80 ft.

Width is 10 ft

Area = length × breadth

So we need to find out the length so

$\frac{8 \cancel{0}}{1 \cancel{0}} \\ \\ = 8ft$

So 8 ft is the length

Now area

$= 8 \times 10 = 80ft$

Hence the area and perimeter of this rectangular field are same i.e. 80 ft.

Answer 2

Answer:

If the perimeter of a rectangular field is 80 ft and its width is 10ft, then the area of this field is 300 sq. ft.

Step-by-step explanation:

Given: The perimeter of a rectangular field = 80 ft

width  =  10ft.

Find the area of this field.

Step 1: Find length by using the perimeter of the rectangle.

The perimeter of rectangle = 2(length + breadth)

2 (length + 10) = 80

length + 10 = 40

length = 40 - 10

length = 30 ft

Step 2: If the length of the rectangle is 30 ft then find the area of the field.

The area of rectangle = length × breadth

=30 × 10

= 300 sq. ft

Hence the area of the field is 300 sq. ft.
